[PATCH 5.8 038/633] ibmvnic: save changed mac address to adapter->mac_addr

From: Greg Kroah-Hartman
Date: Tue Oct 27 2020 - 10:49:31 EST


From: Lijun Pan <ljp@xxxxxxxxxxxxx>

[ Upstream commit d9b0e599b2b892422f1cbc5d2658049b895b2b58 ]

After mac address change request completes successfully, the new mac
address need to be saved to adapter->mac_addr as well as
netdev->dev_addr. Otherwise, adapter->mac_addr still holds old
data.

Fixes: 62740e97881c ("net/ibmvnic: Update MAC address settings after adapter reset")
