====================
macvlan: Avoid unnecessary multicast cloning

This patch tries to improve macvlan multicast performance by
maintaining a filter hash at the macvlan_port level so that we
can quickly determine whether a given packet is needed or not.

It is preceded by a patch that fixes a potential use-after-free
bug that I discovered while looking over this.

v2 fixed a bug where promiscuous/allmulti settings weren't handled
correctly.
