Title:
  11ab:4363 sky2 driver (Marvell Ethernet devices) problem after resume

Status in The Linux Kernel:
  New
Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  After resuming from suspend, a Marvel 88E8055 (wired NIC) will fail to
  detect carrier (link is permanently down). Reloading the sky2 module
  does not help - the module will fail to initialize the hardware and
  the eth0 interfaces is gone until reboot.

  The suspend/resume for this NIC has worked without issues  in 10.10 and some older releases I've had permanently installed. I haven't really tested this with other releases that have come and gone since - which is the best course of action here:
  - testing older releases, or
  - obtaining older kernel versions (from mainline ppa?) and testing those?

  http://marc.info/?l=linux-pm&m=134229404527442&w=2

  WORKAROUND:
  Delete the NIC from the system and have kernel perform a rescan on the PCI bus:
  echo 1 > /sys/class/net/eth0/device/remove ; sleep 1;\
  echo 1 > /sys/class/pci_bus/0000\:00/rescan

  Adjust PCI bus number as appropriate.
