Merge branch 'bonding-next'

Veaceslav Falico says:

====================
bonding: simple macro cleanup

Trivial patchset that converts most of the bonding's macros into inline
functions. It introduces only one macro, BOND_MODE(), which is just
bond->params.mode, better to write/understand/remember.

The only real change is the removal of IFF_UP verification, which always
came in pair with && netif_running(), and is though useless, as it's always
IFF_UP when LINK_STATE_RUNNING.

v2->v3: fix 3/9 to actually invert bond_mode_uses_arp() and add
	bond_uses_arp() alongside bond_mode_uses_arp()
v1->v2: use inlined functions instead of macros.
====================
