Merge branch 'ife-ethertype'

Alexander Aring says:

====================
tc: act_ife: handle IEEE IFE ethertype as default

this patch series will introduce the IFE ethertype which is registered by
IEEE. If the netlink act_ife type netlink attribute is not given it will
use this value by default now.
At least it will introduce some UAPI testcases to check if the default type
is used if not specified and vice versa.
====================
