patch 'net/bnxt: fix IOVA range check for external mbuf' 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 08/01/26. 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/93073fe08fd61baca41ff12ae2f521aa0c286f2e

Thanks.

Kevin

Subject: [PATCH] net/bnxt: fix IOVA range check for external mbuf

[ upstream commit 41f3faf0ce4a062b2bcd08bff68f4b5d2fa7400f ]

For extmem, the mbuf head node may be allocated from a pool
different from the data buffer pool. In that case the IOVA
address check using rte_mempool_virt2iova() will fail. To fix
this, skip the IOVA range check for external mbufs.
Also add unlikely() in checking invalid mbuf size.

Fixes: d01de33f98e2 ("net/bnxt: skip IOVA range check for external mbuf")
