Subject: [net-next PATCH 9/9] octeontx2-af: Add programmed macaddr to RVU pfvf

From: Vidhya Vidhyaraman <Vidhya.Raman@...ium.com>

This commit adds the mac address that is programmed from
application into the RVU pfvf structure. The mac address
retrieval will return the address from RVU pfvf structure.
