Sridhar Samudrala 3f341acc1c i40evf: Fix link state event handling 
Currently disabling the link state from PF via
	ip link set enp5s0f0 vf 0 state disable
doesn't disable the CARRIER on the VF.

This patch updates the carrier and starts/stops the tx queues based on the
link state notification from PF.

  PF: enp5s0f0, VF: enp5s2
  #modprobe i40e
  #echo 2 > /sys/class/net/enp5s0f0/device/sriov_numvfs
  #ip link set enp5s2 up
  #ip -d link show enp5s2
