patch 'net/bonding: fix mbuf fast free handling' has been queued to stable release 21.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/28/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/89f4c06b0feb94e641380f52ba7d6242dcdc10fb

Thanks.

Kevin

Subject: [PATCH] net/bonding: fix mbuf fast free handling

[ upstream commit b4924c0db589b5d4698abfab3ce60978d9df518b ]

The RTE_ETH_TX_OFFLOAD_MBUF_FAST_FREE offload can't be used in bonding
mode Broadcast and mode 8023AD. Currently, bonding driver forcibly removes
from the dev->data->dev_conf.txmode.offloads and processes as success in
bond_ethdev_configure(). But this still cause that rte_eth_dev_configure()
fails to execute because of the failure of validating Tx offload in the
eth_dev_validate_offloads(). So this patch moves the modification of txmode
offlaods to the stage of adding slave device to report the correct txmode
offloads.

Fixes: 18c41457cbae ("net/bonding: fix mbuf fast free usage")
