  cxgb4: notify upper drivers if the device is already up when they load
  cxgb4: keep interrupts available when the ports are brought down
  cxgb4: fix initial addition of MAC address
  cnic: Return SPQ credit to bnx2x after ring setup and shutdown.

Fix up various conflicts with pcmcia tree drivers/net/
{pcmcia/3c589_cs.c, wireless/orinoco/orinoco_cs.c and
wireless/orinoco/spectrum_cs.c} and feature removal
(Documentation/feature-removal-schedule.txt).

Also fix a non-content conflict due to pm_qos_requirement getting
renamed in the PM tree (now pm_qos_request) in net/mac80211/scan.c
