[dpdk-stable] patch 'net/vmxnet3: remove IP checksum from capabilities' has been queued to LTS release 18.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/29/19. 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-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/bdc587ea58e70d0c678b9a08dfeac210e2bf4cb5

Thanks.

Kevin.

Subject: [PATCH] net/vmxnet3: remove IP checksum from capabilities

[ upstream commit 86536da001c03d2bcbdb38ccdcd023e6d744f5b8 ]

The vmxnet3_prep_pkts function set rte_errno to ENOTSUP for any packets
having PKT_TX_IP_CHECKSUM set in ol_flags. But the vmxnet3 has
DEV_TX_OFFLOAD_IPV4_CKSUM set in this tx offload capa.

This issue has been introduced with the new Rx offload
API. DEV_TX_OFFLOAD_IPV4_CKSUM and DEV_RX_OFFLOAD_IPV4_CKSUM has been
added to the tx/rx offloads capa, but the vmxnet3 driver doesn't support
it.

To fix the issue, DEV_TX/RX_OFFLOAD_IPV4_CKSUM needs to be removed from
tx/rx offload capa.

Fixes: 95e4a96ccbf1 ("net/vmxnet3: convert to new Rx offload API")
