With current KPU profile NGIO is being parsed along with CTAG as
a single layer. Because of this MCAM/ntuple rules installed with
ethertype as 0x8842 are not being hit. Adding KPU profile changes
to parse NGIO in separate ltype and CTAG in separate ltype.

PF forwards its VF messages to AF and corresponding
replies from AF to VF. AF sets proper error code in the
replies after processing message requests. Currently PF
checks the error codes in replies and sends invalid
message to VF. This way VF lacks the information of
error code set by AF for its messages. This patch
changes that such that PF simply forwards AF replies
so that VF can handle error codes.

Both versions of the CPSW driver declare a CPSW_HEADROOM_NA macro that
takes NET_IP_ALIGN into account, but fail to use it appropriately when
storing incoming packets in memory. This results in the IPv4 source and
destination addresses to appear misaligned in memory, which causes
aligment faults that need to be fixed up in software.
So let's switch from CPSW_HEADROOM to CPSW_HEADROOM_NA where needed.
This gets rid of any alignment faults on the RX path on a Beaglebone

With previous changes to make the driver handle the TX ring size more
correctly, the default TX ring size of 64 appears to significantly
bottleneck TX performance to around 600 Mbps on a 1 Gbps link on ZynqMP.
Increasing this to 128 seems to bring performance up to near line rate and
shouldn't cause excess bufferbloat (this driver doesn't yet support modern
byte-based queue management).

Network driver documentation indicates we should be avoiding returning
NETDEV_TX_BUSY from ndo_start_xmit in normal cases, since it requires
the packets to be requeued. Instead the queue should be stopped after
a packet is added to the TX ring when there may not be enough room for an
additional one. Also, when TX ring entries are completed, we should only
wake the queue if we know there is room for another full maximally
fragmented packet.
Print a warning if there is insufficient space at the start of start_xmit,
since this should no longer happen.
Combined with increasing the default TX ring size (in a subsequent
patch), this appears to recover the TX performance lost by previous changes
to actually manage the TX ring state properly.

transceiver clock source for the PCS was not running at the time the
FPGA logic was loaded, the core would come up in a state where the
PCS could not be found on the MDIO bus. To fix this, the Ethernet core
(including the PCS) should be reset after enabling the clocks, prior to

When resetting the device, wait for the PhyRstCmplt bit to be set
in the interrupt status register before continuing initialization, to
ensure that the core is actually ready. When using an external PHY, this
also ensures we do not start trying to access the PHY while it is still
in reset. The PHY reset is initiated by the core reset which is
triggered just above, but remains asserted for 5ms after the core is
reset according to the documentation.
The MgtRdy bit could also be waited for, but unfortunately when using
7-series devices, the bit does not appear to work as documented (it
seems to behave as some sort of link state indication and not just an
indication the transceiver is ready) so it can't really be relied on for
this purpose.

The previous timeout of 1ms was too short to handle some cases where the
core is reset just after the input clocks were started, which will
be introduced in an upcoming patch. Increase the timeout to 50ms. Also
simplify the reset timeout checking to use read_poll_timeout.

The reason is that the driver isn't prepared to receive two tc filters
with the same cookie. It unconditionally creates a new struct
ocelot_vcap_filter for each tc filter, and it adds all filters with the
same identifier (cookie) to the ocelot_vcap_block.
The problem is here, in ocelot_vcap_filter_del():
/* Gets index of the filter */
index = ocelot_vcap_block_get_filter_index(block, filter);
if (index < 0)
return index;
/* Delete filter */
ocelot_vcap_block_remove_filter(ocelot, block, filter);
/* Move up all the blocks over the deleted filter */
for (i = index; i < block->count; i++) {
struct ocelot_vcap_filter *tmp;
tmp = ocelot_vcap_block_find_filter_by_index(block, i);
vcap_entry_set(ocelot, i, tmp);
}
what will happen is ocelot_vcap_block_get_filter_index() will return the
index (@index) of the first filter found with that cookie. This is _not_
the index of _this_ filter, but the other one with the same cookie,
because ocelot_vcap_filter_equal() gets fooled.
Then later, ocelot_vcap_block_remove_filter() is coded to remove all
filters that are ocelot_vcap_filter_equal() with the passed @filter.
So unexpectedly, both filters get deleted from the list.
Then ocelot_vcap_filter_del() will attempt to move all the other filters
up, again finding them by index (@i). The block count is 2, @index was 0,
so it will attempt to move up filter @i=0 and @i=1. It assigns tmp =
ocelot_vcap_block_find_filter_by_index(block, i), which is now a NULL
pointer because ocelot_vcap_block_remove_filter() has removed more than
one filter.
As far as I can see, this problem has been there since the introduction
of tc offload support, however I cannot test beyond the blamed commit
due to hardware availability. In any case, any fix cannot be backported
that far, due to lots of changes to the code base.
Therefore, let's go for the correct solution, which is to not call
ocelot_vcap_filter_add() and ocelot_vcap_filter_del(), unless the filter
is actually unique and not shared. For the shared filters, we should
just modify the ingress port mask and call ocelot_vcap_filter_replace(),
a function introduced by commit 95706be13b9f ("net: mscc: ocelot: create
a function that replaces an existing VCAP filter"). This way,
block->rules will only contain filters with unique cookies, by design.
