[dpdk-stable] patch 'drivers/net: fix several Tx prepare functions' has been queued to stable release 18.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 18.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/18/18. 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.

Thanks.

Kevin Traynor

Subject: [PATCH] drivers/net: fix several Tx prepare functions

[ upstream commit d6db681bf9b8095da2fed653ec5b89e5f165eaa8 ]

Since below commit, several tx_prep functions are broken, they fail to
pass supported Tx offload features check:
PKT_TX_IPVx must be set when any PKT_TX_L4 checksum is requested,
but these values are not present in the mask of supported Tx offloads
of several drivers that advertise PKT_TX_L4_MASK.
So any packet sent to those drivers with a L4 checksum request and
one of PKT_TX_IPVx bit set is rejected by the tx prepare function.

Fixes: 1037ed842c37 ("mbuf: fix Tx offload mask")
