Subject: [iwl next-queue PATCH 00/10] Clean-up macvlan offloading

This patch set represents yet another phase of the macvlan cleanup I have
been working on.

The main goal of these changes is to make it so that we only support
offloading what we can actually offload and we don't break any existing
functionality. So for example we were claiming to advertise source mode
macvlan and we were doing nothing of the sort, so support for that has been
dropped.

The biggest change with this set is that broadcast/multicast replication is
no longer being supported in software. I am dropping it as it leads to
scaling issues when a broadcast frame has to be replciated up to 64 times.

Beyond that this set goes through and optimized the time needed to bring up
and tear down the macvlan interfaces on ixgbe and provides a clean way for
us to disable the macvlan offload when needed.
