Subject: [net-next 04/14] i40evf: remove aq_pending
From: Mitch Williams <mitch.a.williams@...el.com>
The aq_pending field in the adapter structure is actually redundant with
the current_op field. Remove the aq_pending field and expunge all traces
of it from the official record. This simplifies the code significantly,
especially in the virtual channel completion routine.
