patch 'net/enetc: fix Tx BD structure' has been queued to stable release 25.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/04/26. 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/1ab0629c0955b14c2604915fa6eed0137ce7172a

Thanks.

Kevin

Subject: [PATCH] net/enetc: fix Tx BD structure

[ upstream commit 22baba08f3439a7e20ced171bec67f789399f183 ]

The flags field in struct enetc_tx_bd was declared as uint16_t but
ENETC4 TX BDs only use an 8-bit flags byte. Fix the type to uint8_t
to match the hardware descriptor layout.

Fixes: 696fa399d797 ("net/enetc: add PMD with basic operations")
