patch 'net/txgbe: fix FDIR rule raw relative for L3 packets' has been queued to stable release 24.11.4

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 24.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/26/25. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/ba28c5021f4a9c877b161b025b7d06c48aad3c55

Thanks.

Kevin

Subject: [PATCH] net/txgbe: fix FDIR rule raw relative for L3 packets

[ upstream commit f1cd458035da9066379c457d27488eeb7741af46 ]

Hardware supports FDIR flex field base setting from start of MAC header,
IP header, L4 header, L4 payload. So for IP packet which has no L4 header,
it cannot match the raw bytes with relative offset start from L3 payload.
And FDIR flex bytes rule cannot match L2 packets.

Therefore, we will declare that the relative offset is only used for
matching the L4 packets.

Fixes: aa4974765499 ("net/txgbe: fix raw pattern match for FDIR rule")
