From 54f455eeb56c0ab92db87bed6bd767d206d9e743 Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Mon, 27 Apr 2015 14:57:14 -0400 Subject: [PATCH] i40e: do a proper reset when disabling a VF The VF disable code was just whanging on the reset bit without properly cleaning up the VF, which would leave the VF in an indeterminate state from which it could not recover. Fix this by notifying the VF and then by calling the normal VF reset routine.
