[ Upstream commit d084d996aaf53c0cc583dc75a4fc2a67fe485846 ]
When feature VIRTIO_NET_F_MTU is negotiated on mlx5_vdpa,
22 extra bytes worth of MTU length is shown in guest.
This is because the mlx5_query_port_max_mtu API returns
the "hardware" MTU value, which does not just contain the
Ethernet payload, but includes extra lengths starting
from the Ethernet header up to the FCS altogether.
Fix the MTU so packets won't get dropped silently.

used in several places in the driver, where a TX half duplex transfer
is sufficient.

introduces a new function mcp251x_spi_write() and changes all callers
that do a TX half duplex transfer to use mcp251x_spi_write().

Since commit 14d3d54052539a1e ("perf session: Try to read pipe data from
file") 'perf inject' has started printing "PERFILE2h" when not processing
pipes.
The commit exposed perf to the possiblity that the input is not a pipe
but the 'repipe' parameter gets used. That causes the printing because
perf inject sets 'repipe' to true always.
The 'repipe' parameter of perf_session__new() is used by 2 functions:
- perf_file_header__read_pipe()
- trace_report()
In both cases, the functions copy data to STDOUT_FILENO when 'repipe' is
true.
Fix by setting 'repipe' to true only if the output is a pipe.

We should set the platform device's driver data to NULL here so that
code doesn't assume the struct drm_device pointer is valid when it could
have been destroyed. The lifetime of this pointer is managed by a kref
but when msm_drm_init() fails we call drm_dev_put() on the pointer which
will free the pointer's memory. This driver uses the component model, so
there's sort of two "probes" in this file, one for the platform device
i.e. msm_pdev_probe() and one for the component i.e. msm_drm_bind(). The
msm_drm_bind() code is using the platform device's driver data to store
struct drm_device so the two functions are intertwined.
This relationship becomes a problem for msm_pdev_shutdown() when it
tests the NULL-ness of the pointer to see if it should call
drm_atomic_helper_shutdown(). The NULL test is a proxy check for if the
pointer has been freed by kref_put(). If the drm_device has been
destroyed, then we shouldn't call the shutdown helper, and we know that
is the case if msm_drm_init() failed, therefore set the driver data to
NULL so that this pointer liveness is tracked properly.

If veb-stats was enabled, the ethtool stats triggered a warning
due to invalid size: 'unexpected stat size for veb.tc_%u_tx_packets'.
This was due to an incorrect structure definition for the statistics.
Structures and functions have been improved in line with requirements
for the presentation of statistics, in particular for the functions:
'i40e_add_ethtool_stats' and 'i40e_add_stat_strings'.

on struct qm_eqcr_entry conflicts with the 8-byte alignment
attribute on struct qm_fd inside it:
drivers/soc/fsl/qbman/qman.c:189:1: error: alignment 1 of 'struct qm_eqcr_entry' is less than 8 [-Werror=packed-not-aligned]
I assume that the alignment attribute is the correct one, and
that qm_eqcr_entry cannot actually be unaligned in memory,
so add the same alignment on the outer struct.

ct_label 0 is a default label each flow has and therefore
there can be rules that match on ct_label=0 without a prior
rule that set the ct_label to this value.
The ct_label value is not used directly in the HW rules and
instead it is mapped to some id within a defined range and this
id is used to set and match the metadata register which carries
the ct_label.
If we have a rule that matches on ct_label=0, the hw rule will
perform matching on a value that is != 0 because of the mapping
from label to id. Since the metadata register default value is
0 and it was never set before to anything else by an action that
sets the ct_label, there will always be a mismatch between that
register and the value in the rule.
To support such rule, a forced mapping of ct_label 0 to id=0
is done so that it will match the metadata register default
value of 0.

Calling ncsi_stop_channel_monitor from channel_monitor is a guaranteed
deadlock on SMP because stop calls del_timer_sync on the timer that
invoked channel_monitor as its timer function.
Recognise the inherent race of marking the monitor disabled before
deleting the timer by just returning if enable was cleared. After
a timeout (the default case -- reset to START when response received)
just mark the monitor.enabled false.
If the channel has an entry on the channel_queue list, or if the
state is not ACTIVE or INACTIVE, then warn and mark the timer stopped
and don't restart, as the locking is broken somehow.

In the if(skb_peek(arrvq) == skb) branch, it calls __skb_dequeue(arrvq) to get
the skb by skb = skb_peek(arrvq). Then __skb_dequeue() unlinks the skb from arrvq
and returns the skb which equals to skb_peek(arrvq). After __skb_dequeue(arrvq)
finished, the skb is freed by kfree_skb(__skb_dequeue(arrvq)) in the first time.
Unfortunately, the same skb is freed in the second time by kfree_skb(skb) after
the branch completed.
My patch removes kfree_skb() in the if(skb_peek(arrvq) == skb) branch, because
this skb will be freed by kfree_skb(skb) finally.

Cited commit changed the behavior of the software data path with regards
to the ECN marking of decapsulated packets. However, the commit did not
change other callers of __INET_ECN_decapsulate(), namely mlxsw. The
driver is using the function in order to ensure that the hardware and
software data paths act the same with regards to the ECN marking of
decapsulated packets.
The discrepancy was uncovered by commit 5aa3c334a449 ("selftests:
forwarding: vxlan_bridge_1d: Fix vxlan ecn decapsulate value") that
aligned the selftest to the new behavior. Without this patch the
selftest passes when used with veth pairs, but fails when used with
mlxsw netdevs.
Fix this by instructing the device to propagate the ECT(1) mark from the
outer header to the inner header when the inner header is ECT(0), for
both NVE and IP-in-IP tunnels.
A helper is added in order not to duplicate the code between both tunnel
types.
