====================
Intel Wired LAN Driver Updates 2014-10-30

This series contains updates to e1000, igb and ixgbe.

Francesco Ruggeri fixes an issue with e1000 where in a VM the driver did
not support unicast filtering.

Roman Gushchin fixes an issue with igb where the driver was re-using
mapped pages so that packets were still getting dropped even if all
the memory issues are gone and there is free memory.

Junwei Zhang found where in the ixgbe_clean_rx_ring() we were repeating
the assignment of NULL to the receive buffer skb and fixes it.

Emil fixes a race condition between setup_link and SFP detection routine
in the watchdog when setting the advertised speed.
