We find that VF receive address register is not set
if MAC address is assigned by PF. This patch fixes it.

A little confused about the Fixes. You said this patch is for when mac address is set by PF. But the fixes said the previous patch is for not set by PF. Seems they're different scenarios. Why this can a fix for a different scenario?
Thanks.

Previous patch only do rar set when random a MAC for VF, when MAC address is
assigned by PF, register is not set.
Maybe I should correct the fix line, the issue I fixed is exist before 2a3cf07108b4.
