[dpdk-dev] [PATCH 3/7] net/iavf: fix port start during configuration restore

[SteveX Yang]

If configuring VF promiscuous mode is not supported,
return -ENOTSUP error code in .promiscuous_enable/disable dev_ops.
This is to fix the port start during configuration restore,
where if .promiscuous_enable/disable dev_ops exists
and return any value other than -ENOTSUP, start will fail.

Same is done for .allmulticast_enable/disable dev_ops.

Fixes: ca041cd44fcc ("ethdev: change allmulticast callbacks to return status")
Fixes: 9039c8125730 ("ethdev: change promiscuous callbacks to return status")
