patch 'net/sfc: account for data offset on Tx' has been queued to stable release 21.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/08/23. 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/0ea692c019ba9271499d658bae1cee724a849a20

Thanks.

Kevin

Subject: [PATCH] net/sfc: account for data offset on Tx

[ upstream commit e7694b080de025fbc4bb31fbe7eb149f20a10373 ]

Memory buffers passed by the application may contain private data,
which must not be sent to the NIC. Omit this private data by using
the actual data address instead of the default one.

Fixes: 3037e6cf3dde ("net/sfc: support regioned NIC DMA memory mapping type")
