Subject: net: hns3: PF enable promisc for VF when mac table is overflow
Patch-mainline: v5.15-rc4
Git-commit: 276e60421668d019dc655973b1832ea354c0f36c
References: bsc#1190336

If unicast mac address table is full, and user add a new mac address, the
unicast promisc needs to be enabled for the new unicast mac address can be
used. So does the multicast promisc.

Now this feature has been implemented for PF, and VF should be implemented
too. When the mac table of VF is overflow, PF will enable promisc for this
VF.

Fixes: 1e6e76101fd9 ("net: hns3: configure promisc mode for VF asynchronously")
