From: Vasu Dev <vasu....@intel.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit cb78cf12d6e90f57f6e7d090867ef19b6a189dde upstream.
PFC is configuration is skipped for X550 devices due to a incorrect
device id check, fixing that to include X550 PFC configuration.
