Hi,

FYI, your patch has been queued to stable release 20.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/23/22. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/628b8d88c48c3679daf1ae2e7a42933c5ad5401a

Thanks.

[ upstream commit 2ee8c67ef9399759cb0d3f34b2c9fb6ea0ecc832 ]

eth_hw_addr_random() sets address type correctly.

eth_hw_addr_random() is available since Linux v3.4, so
no compat is required.

Also fix the warning:
warning: passing argument 1 of ‘memcpy’ discards ‘const’
qualifier from pointer target type

Variable dev_addr is done const intentionally in Linux v5.17 to
prevent using it directly.

Fixes: ea6b39b5b847 ("kni: remove ethtool support")
