[NET 00/05]: netdevice rx mode synchronization fixes + macvlan driver

[Patrick McHardy <kaber@trash.net>]

These patches introduce a new net_device hook for synchronizing promiscous
and allmulti state to an underlying device (as done by 8021q, bonding,
maxvlan, ..) to fix some races that occur when doing this from
dev->set_multicast_list. They also introduce two helpers for multicast
list synchonization and change VLAN to make use of all of this (mainly to
show that its not only for macvlan, but it also fixes some real races).
The last patch adds the macvlan driver.

Please apply, thanks.
