Pull networking fixes from David Miller:

 1) Fix NBMA tunnel mac header handling in GRE, from Timo Teräs.

 2) Fix a NAPI race in the fec driver, from Nimrod Andy.

 3) The new IFF_VNET_LE bit is outside the size of the flags member it
    is stored in (which is 16-bits), store the state locally in the
    drivers.  From Michael S Tsirkin.

 4) We are kicking the tires with the new wireless maintainership
    situation.  Bluetooth fixes via Johan Hedberg, and mac80211 fixes
    from Johannes Berg.

 5) Fix locking and leaks in geneve driver, from Jesse Gross.

 6) Make netlink TX mmap code always copy, so we don't have to be
    potentially exposed to the user changing the underlying contents
    from underneath us.
