Subject: [next PATCH 00/11] ixgbe: Add support for mixed PF/VF virtualization

This patch series extends the abilities of the ixgbe driver so that we can
now support VLAN trunking on top of the PF when SR-IOV is enabled.  By
doing this we are able to extend the existing capabilities that were
enabled with the "bridge fdb add" support that was added some time ago.  It
had enabled the ability to have PF and VF mixed on a flat network, this
makes it so that it also works on a VLAN enabled network.

The first few patches in this series are basically just cleanup.  They
either fix bugs found in the code, or address complexity that was making it
hard to either read or sort out exactly how the code was supposed to work.

The second half of the patch set is where we start adding features.
Specifically with this patch set the VLAN behavior changes for the PF in
two ways.  First we do not need to use the VLVF if the VFs have not already
set up a pool list.  As such I added functionality so that we can skip that
step when it is not needed.  Then I added support for VLAN promiscuous by
simply setting all of the bits in the VFTA and letting the packets fall
through to the default pool.  In addition when in promiscuous mode we set
the pool bit for the PF in all of the VLVF entries.  This way if anyone
adds a new entry it will automatically have the PF enabled.

The last few patches address some more issues I found during testing.  The
issues were primarily related to stale entries floating around in either
the RAR or VLVFB registers which were pointing to pools which were not
valid for the given L2 address.
