Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/13/26. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/d604a391f3aaa030e19d6bcd3d462d278b605cfe

Thanks.

Luca Boccassi

Subject: [PATCH] net/i40e: fix simple Tx prepare rejecting tunnel type flags

[ upstream commit b66eb5a4816195ffed51f6dd6df4836c1b1f9776 ]

The tunnel type bits in ol_flags (RTE_MBUF_F_TX_TUNNEL_*) identify
the encapsulation protocol used by a packet. An application may set
these to indicate tunnel type without requesting any tunnel offload.
The simple Tx path was incorrectly treating these flags as unsupported
offload requests and rejecting the packet.

Add RTE_MBUF_F_TX_TUNNEL_MASK to the set of permitted flags in the
simple Tx supported offloads mask to permit tunnel flags in the mbuf.

Bugzilla ID: 1342
Fixes: 146ffa81d05e ("net/i40e: add Tx preparation for simple Tx datapath")
