Merge branch 'Aquantia-various-patches-2018-05' 

Igor Russkikh says:

====================
Aquantia various patches 2018-05

These are two patches covering issues found during test cycles:

First is that driver should declare valid vlan_features
Second fix is about correct allocation of MSI interrupts on some systems.
====================
