commit 1ce2654d87e2fb91fea83b288bd9b2641045e42a upstream.
DDPP is copied from Synopsys Data book:
DDPP: Disable Data path Parity Protection.
When it is 0x0, Data path Parity Protection is enabled.
When it is 0x1, Data path Parity Protection is disabled.
The macro name should be XGMAC_DPP_DISABLE.

commit 1692b9775e745f84b69dc8ad0075b0855a43db4e upstream.
The cited commit introduces and uses the string constants dpp_tx_err and
dpp_rx_err. These are assigned to constant fields of the array
dwxgmac3_error_desc.
It has been reported that on GCC 6 and 7.5.0 this results in warnings
such as:
.../dwxgmac2_core.c:836:20: error: initialiser element is not constant
{ true, "TDPES0", dpp_tx_err },
I have been able to reproduce this using: GCC 7.5.0, 8.4.0, 9.4.0 and 10.5.0.
But not GCC 13.2.0.
So it seems this effects older compilers but not newer ones.
As Jon points out in his report, the minimum compiler supported by
the kernel is GCC 5.1, so it does seem that this ought to be fixed.
It is not clear to me what combination of 'const', if any, would address
this problem. So this patch takes of using #defines for the string
constants
Compile tested only.

For XDP_TX action xdp_buff is converted to xdp_frame. The conversion is
done by xdp_convert_buff_to_frame(). The memory type of the resulting
xdp_frame depends on the memory type of the xdp_buff. For page pool
based xdp_buff it produces xdp_frame with memory type
MEM_TYPE_PAGE_POOL. For zero copy XSK pool based xdp_buff it produces
xdp_frame with memory type MEM_TYPE_PAGE_ORDER0.
tsnep_xdp_xmit_back() is not prepared for that and uses always the page
pool buffer type TSNEP_TX_TYPE_XDP_TX. This leads to invalid mappings
and the transmission of undefined data.
Improve tsnep_xdp_xmit_back() to use the generic buffer type
TSNEP_TX_TYPE_XDP_NDO for zero copy XDP_TX.

[ Upstream commit bc90fbe0c3182157d2be100a2f6c2edbb1820677 ]
Currently the teardown/setup flow for driver probe/remove is quite
a bit different from the reset flows in pdsc_fw_down()/pdsc_fw_up().
One key piece that's missing are the calls to pci_alloc_irq_vectors()
and pci_free_irq_vectors(). The pcie reset case is calling
pci_free_irq_vectors() on reset_prepare, but not calling the
corresponding pci_alloc_irq_vectors() on reset_done. This is causing
unexpected/unwanted interrupt behavior due to the adminq interrupt
being accidentally put into legacy interrupt mode. Also, the
pci_alloc_irq_vectors()/pci_free_irq_vectors() functions are being
called directly in probe/remove respectively.
Fix this inconsistency by making the following changes:
1. Always call pdsc_dev_init() in pdsc_setup(), which calls
pci_alloc_irq_vectors() and get rid of the now unused
pds_dev_reinit().
2. Always free/clear the pdsc->intr_info in pdsc_teardown()
since this structure will get re-alloced in pdsc_setup().
3. Move the calls of pci_free_irq_vectors() to pdsc_teardown()
since pci_alloc_irq_vectors() will always be called in
pdsc_setup()->pdsc_dev_init() for both the probe/remove and
reset flows.
4. Make sure to only create the debugfs "identity" entry when it
doesn't already exist, which it will in the reset case because
it's already been created in the initial call to pdsc_dev_init().

[ Upstream commit 7e82a8745b951b1e794cc780d46f3fbee5e93447 ]
There are multiple paths that can result in using the pdsc's
adminq.
[1] pdsc_adminq_isr and the resulting work from queue_work(),
i.e. pdsc_work_thread()->pdsc_process_adminq()
[2] pdsc_adminq_post()
When the device goes through reset via PCIe reset and/or
a fw_down/fw_up cycle due to bad PCIe state or bad device
state the adminq is destroyed and recreated.
A NULL pointer dereference can happen if [1] or [2] happens
after the adminq is already destroyed.
In order to fix this, add some further state checks and
implement reference counting for adminq uses. Reference
counting was used because multiple threads can attempt to
access the adminq at the same time via [1] or [2]. Additionally,
multiple clients (i.e. pds-vfio-pci) can be using [2]
at the same time.
The adminq_refcnt is initialized to 1 when the adminq has been
allocated and is ready to use. Users/clients of the adminq
(i.e. [1] and [2]) will increment the refcnt when they are using
the adminq. When the driver goes into a fw_down cycle it will
set the PDSC_S_FW_DEAD bit and then wait for the adminq_refcnt
to hit 1. Setting the PDSC_S_FW_DEAD before waiting will prevent
any further adminq_refcnt increments. Waiting for the
adminq_refcnt to hit 1 allows for any current users of the adminq
to finish before the driver frees the adminq. Once the
adminq_refcnt hits 1 the driver clears the refcnt to signify that
the adminq is deleted and cannot be used. On the fw_up cycle the
driver will once again initialize the adminq_refcnt to 1 allowing
the adminq to be used again.

[ Upstream commit 951705151e50f9022bc96ec8b3fd5697380b1df6 ]
The initial design for the adminq interrupt was done based
on client drivers having their own adminq and adminq
interrupt. So, each client driver's adminq isr would use
their specific adminqcq for the private data struct. For the
time being the design has changed to only use a single
adminq for all clients. So, instead use the struct pdsc for
the private data to simplify things a bit.
This also has the benefit of not dereferencing the adminqcq
to access the pdsc struct when the PDSC_S_STOPPING_DRIVER bit
is set and the adminqcq has actually been cleared/freed.

[ Upstream commit f1f6a6b1830a8f1dc92ee26fae76333f446b0663 ]
The e1000e driver supports hardware with a variety of different clock
speeds, and thus a variety of different increment values used for
programming its PTP hardware clock.
The values currently programmed in e1000e_ptp_init are incorrect. In
particular, only two maximum adjustments are used: 24000000 - 1, and
600000000 - 1. These were originally intended to be used with the 96 MHz
clock and the 25 MHz clock.
Both of these values are actually slightly too high. For the 96 MHz clock,
the actual maximum value that can safely be programmed is 23,999,938. For
the 25 MHz clock, the maximum value is 599,999,904.
Worse, several devices use a 24 MHz clock or a 38.4 MHz clock. These parts
are incorrectly assigned one of either the 24million or 600million values.
For the 24 MHz clock, this is not a significant issue: its current
increment value can support an adjustment up to 7billion in the positive
direction. However, the 38.4 KHz clock uses an increment value which can
only support up to 230,769,157 before it starts overflowing.
To understand where these values come from, consider that frequency
adjustments have the form of:
new_incval = base_incval + (base_incval * adjustment) / (unit of adjustment)
The maximum adjustment is reported in terms of parts per billion:
new_incval = base_incval + (base_incval * adjustment) / 1 billion
The largest possible adjustment is thus given by the following:
max_incval = base_incval + (base_incval * max_adj) / 1 billion
Re-arranging to solve for max_adj:
max_adj = (max_incval - base_incval) * 1 billion / base_incval
We also need to ensure that negative adjustments cannot underflow. This can
be achieved simply by ensuring max_adj is always less than 1 billion.
Introduce new macros in e1000.h codifying the maximum adjustment in PPB for
each frequency given its associated increment values. Also clarify where
these values come from by commenting about the above equations.
Replace the switch statement in e1000e_ptp_init with one which mirrors the
increment value switch statement from e1000e_get_base_timinica. For each
device, assign the appropriate maximum adjustment based on its frequency.
Some parts can have one of two frequency modes as determined by
E1000_TSYNCRXCTL_SYSCFI.
Since the new flow directly matches the assignments in
e1000e_get_base_timinca, and uses well defined macro names, it is much
easier to verify that the resulting maximum adjustments are correct. It
also avoids difficult to parse construction such as the "hw->mac.type <
e1000_phc_lpt", and the use of fallthrough which was especially confusing
when combined with a conditional block.
Note that I believe the current increment value configuration used for
24MHz clocks is sub-par, as it leaves at least 3 extra bits available in
the INCVALUE register. However, fixing that requires more careful review of
the clock rate and associated values.

While converting to FIELD_PREP() and FIELD_GET(), it was noticed that
some of the RSS defines had *included* the shift in their definitions.
This is completely outside of normal, such that a developer could easily
make a mistake and shift at the usage site (like when using
FIELD_PREP()).
Rename the defines and set them to the "pre-shifted values" so they
match the template the driver normally uses for masks and the member

Driver has a logic leak in ring data allocation/free,
where aq_ring_free could be called multiple times on same ring,
if system is under stress and got memory allocation error.
Ring pointer was used as an indicator of failure, but this is
not correct since only ring data is allocated/deallocated.
Ring itself is an array member.
Changing ring allocation functions to return error code directly.
This simplifies error handling and eliminates aq_ring_free

xdp_rxq_info struct can be registered by drivers via two functions -
xdp_rxq_info_reg() and __xdp_rxq_info_reg(). The latter one allows
drivers that support XDP multi-buffer to set up xdp_rxq_info::frag_size
which in turn will make it possible to grow the packet via
bpf_xdp_adjust_tail() BPF helper.
Currently, ice registers xdp_rxq_info in two spots:
1) ice_setup_rx_ring() // via xdp_rxq_info_reg(), BUG
2) ice_vsi_cfg_rxq() // via __xdp_rxq_info_reg(), OK
Cited commit under fixes tag took care of setting up frag_size and
updated registration scheme in 2) but it did not help as
1) is called before 2) and as shown above it uses old registration
function. This means that 2) sees that xdp_rxq_info is already
registered and never calls __xdp_rxq_info_reg() which leaves us with
xdp_rxq_info::frag_size being set to 0.
To fix this misbehavior, simply remove xdp_rxq_info_reg() call from
ice_setup_rx_ring().

XDP programs can shrink packets by calling the bpf_xdp_adjust_tail()
helper function. For multi-buffer packets this may lead to reduction of
frag count stored in skb_shared_info area of the xdp_buff struct. This
results in issues with the current handling of XDP_PASS and XDP_DROP
cases.
For XDP_PASS, currently skb is being built using frag count of
xdp_buffer before it was processed by XDP prog and thus will result in
an inconsistent skb when frag count gets reduced by XDP prog. To fix
this, get correct frag count while building the skb instead of using
pre-obtained frag count.
For XDP_DROP, current page recycling logic will not reuse the page but
instead will adjust the pagecnt_bias so that the page can be freed. This
again results in inconsistent behavior as the page refcnt has already
been changed by the helper while freeing the frag(s) as part of
shrinking the packet. To fix this, only adjust pagecnt_bias for buffers
that are stillpart of the packet post-xdp prog run.

Fix an OOM panic in XDP_DRV mode when a XDP program shrinks a
multi-buffer packet by 4k bytes and then redirects it to an AF_XDP
socket.
Since support for handling multi-buffer frames was added to XDP, usage
of bpf_xdp_adjust_tail() helper within XDP program can free the page
that given fragment occupies and in turn decrease the fragment count
within skb_shared_info that is embedded in xdp_buff struct. In current
ice driver codebase, it can become problematic when page recycling logic
decides not to reuse the page. In such case, __page_frag_cache_drain()
is used with ice_rx_buf::pagecnt_bias that was not adjusted after
refcount of page was changed by XDP prog which in turn does not drain
the refcount to 0 and page is never freed.
To address this, let us store the count of frags before the XDP program
was executed on Rx ring struct. This will be used to compare with
current frag count from skb_shared_info embedded in xdp_buff. A smaller
value in the latter indicates that XDP prog freed frag(s). Then, for
given delta decrement pagecnt_bias for XDP_DROP verdict.
While at it, let us also handle the EOP frag within
ice_set_rx_bufs_act() to make our life easier, so all of the adjustments
needed to be applied against freed frags are performed in the single
place.

[ Upstream commit f7f6aa8e24383fbb11ac55942e66da9660110f80 ]
XDP multi-buffer support introduced XDP_FLAGS_HAS_FRAGS flag that is
used by drivers to notify data path whether xdp_buff contains fragments
or not. Data path looks up mentioned flag on first buffer that occupies
the linear part of xdp_buff, so drivers only modify it there. This is
sufficient for SKB and XDP_DRV modes as usually xdp_buff is allocated on
stack or it resides within struct representing driver's queue and
fragments are carried via skb_frag_t structs. IOW, we are dealing with
only one xdp_buff.
ZC mode though relies on list of xdp_buff structs that is carried via
xsk_buff_pool::xskb_list, so ZC data path has to make sure that
fragments do *not* have XDP_FLAGS_HAS_FRAGS set. Otherwise,
xsk_buff_free() could misbehave if it would be executed against xdp_buff
that carries a frag with XDP_FLAGS_HAS_FRAGS flag set. Such scenario can
take place when within supplied XDP program bpf_xdp_adjust_tail() is
used with negative offset that would in turn release the tail fragment
from multi-buffer frame.
Calling xsk_buff_free() on tail fragment with XDP_FLAGS_HAS_FRAGS would
result in releasing all the nodes from xskb_list that were produced by
driver before XDP program execution, which is not what is intended -
only tail fragment should be deleted from xskb_list and then it should
be put onto xsk_buff_pool::free_list. Such multi-buffer frame will never
make it up to user space, so from AF_XDP application POV there would be
no traffic running, however due to free_list getting constantly new
nodes, driver will be able to feed HW Rx queue with recycled buffers.
Bottom line is that instead of traffic being redirected to user space,
it would be continuously dropped.
To fix this, let us clear the mentioned flag on xsk_buff_pool side
during xdp_buff initialization, which is what should have been done
right from the start of XSK multi-buffer support.

as zero immediately after the reset is de-asserted, also adding several
no-ops is not enough, adding a printk is enough, also udelay(1) seems to
be enough but I tried that not very often, and I have not access to many

When FW provides ICM addresses for drop RX/TX, the provided capability
is 64 bits that contain its GVMI as well as the ICM address itself.
In case of TX DROP this GVMI is different from the GVMI that the
domain is operating on.
This patch fixes the action to use these GVMI IDs, as provided by FW.

To enable multicast packets which are offloaded in bridge multicast
offload mode to be sent also to uplink, FTE bit uplink_hairpin_en should
be set. Add this bit to FTE for the bridge multicast offload rules.
