Subject: ixgbevf: Link lost in VM on ixgbevf when restoring from freeze or
 suspend
Patch-mainline: v5.4-rc1
Git-commit: d7cb9da1864d0986d5fca550e20c608d8616ff52
References: jsc#SLE-7979 jsc#SLE-7981

This patch fixed issue in VM which shows no link when hypervisor is
restored from low-power state. The driver is responsible for re-enabling
any features of the device that had been disabled during suspend calls,
such as IRQs and bus mastering.
