Merge branch 'netdev_tx_t'

Luc Van Oostenryck says:

====================
net: always use netdev_tx_t for xmit()'s return type

The ndo_start_xmit() methods should return a 'netdev_tx_t', not
an int, and so should return NETDEV_TX_OK, not 0.
The patches in the series fix most of the remaning drivers and
subsystems (those included in allyesconfig on x86).
====================
