Subject: [PATCH net-next] liquidio VF: fix incorrect struct being used

From: Prasad Kanneganti <prasad.kanneganti@...ium.com>

The VF driver is using the wrong struct when sending commands to the NIC
firmware, sometimes causing adverse effects in the firmware.  The right
struct is the one that the PF is using, so make the VF use that as well.
