patch 'net/mlx5: fix inline length for multi-segment TSO' has been queued to stable release 20.11.5

Hi,

FYI, your patch has been queued to stable release 20.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/20/22. 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/c9eb38cd065bfc2cdb9bdefc37863cd37595c1d7

Thanks.

Luca Boccassi

Subject: [PATCH] net/mlx5: fix inline length for multi-segment TSO

[ upstream commit 864678e420f00225572be476559a087bfecaafbf ]

This patch removes a redundant assert in mlx5_tx_packet_multi_tso().
That assert assured that the amount of bytes requested to be inlined
is greater than or equal to the minimum amount of bytes required
to be inlined. This requirement is either derived from the NIC
inlining mode or configured through devargs. When using TSO this
requirement can be disregarded, because on all NICs it is satisfied by
TSO inlining requirements, since TSO requires L2, L3, and L4 headers to
be inlined.

Fixes: 18a1c20044c0 ("net/mlx5: implement Tx burst template")
