[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/14/22. 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/a6025189d23ece5b16198364c0c75726a55d9181

Subject: [PATCH] net/kni: fix config initialization

[ upstream commit dcd398f9466fc42f09e5c725c3188d8c41bd3fbf ]

When kni driver calls eth_kni_start to start device, some fields such as
min_mtu and max_mtu of rte_kni_conf are not initialized. It will cause
kni_ioctl_create create a kni netdevice with a random min_mtu and
max_mtu value. This is unexpected and sometimes we could not change the
kni device mtu with ip link command.

Fixes: ff1e35fb5f83 ("kni: calculate MTU from mbuf size")
