This patch stops PF from sending message to VF when VF's ARQ and ATQ
isn't enabled, namely VF isn't up and modifies VF state to active when
VF reset is completed.
Fixes: 4861cde46116 ("i40e: new poll mode driver")

Abbreviation is not easy to understand, how about changing ARQ and ATQ with admin queue?
