[dpdk-stable] patch 'net/i40e: revert fix offload not supported mask' has been queued to LTS release 17.11.6

[Yongseok Koh]

Hi,

FYI, your patch has been queued to LTS release 17.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objection by 03/13/19. So please
shout if anyone has objection.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Yongseok

Subject: [PATCH] net/i40e: revert fix offload not supported mask

[ upstream commit e51da4bbaf3584e16cbd0ea0b1b85343b777134f ]

This reverts
commit 09a62d75691f ("net/i40e: fix offload not supported mask")

Contrary to what is said in above patch commit log,
I40E_TX_OFFLOAD_NOTSUP_MASK is the mask of Tx offload bits that are part
of PKT_TX_OFFLOAD_MASK but not included in I40E_TX_OFFLOAD_MASK.
Above patch erroneously includes all PKT_RX_OFFLOAD_ bits in the
I40E_TX_OFFLOAD_NOTSUP_MASK, this is not what is expected.
Restore the initial xor that gives the expected result.

Fixes: 09a62d75691f ("net/i40e: fix offload not supported mask")
