The PF was not correctly registering any of its VLANs. As a result any
VLAN tagged traffic from the VF would not be delivered to the PF because
the VLAN was never assigned to the PF pool.
In addition the VF was not allowed to receive traffic from VLAN 0 if it was
allowed to receive untagged frames. This change corrects that so that it
will correctly receive traffic from VLAN 0.

This patch does two things. First it drops the unnecessary work of
searching for enabled VFs when we first bring up the adapter and instead
just uses pci_num_vf to determine how many VFs are enabled on the adapter.
The second thing it does is drop the use of vfdev from the vf_data_storage
structure. Instead we just search the entire system for a VF that has us
as it's PF, and then if that VF is assigned we indicate that the VFs are
assigned. This allows us to still check for assigned VFs even if the
vfinfo allocation has failed, or vfinfo has been freed.

This is meant to fix a bug in which we were not checking for pre-existing
VFs if we were not setting the max_vfs value at driver load. What happens
now is that we always call ixgbe_enable_sriov and this checks for
pre-existing VFs ore requested VFs prior to deciding on no SR-IOV.

The VF driver had a memory leak that would occur if VFs were assigned to a
guest. The amount of leak would vary with the number of VFs but could max
out at about 14K per PF. To reproduce the leak all you would need to do is
enable all the VFs on the first PF. Then start a loop of loading and
unloading the driver with max_vfs=63 for the first port.

This change makes it so that we can use the VMDq ring feature offset value
to determine the default pool instead of using num_vfs. The reason for
this change is to avoid issues should we fail to allocate vfinfo but have
pre-existing VFs. What should happen in this case is that num_vfs will go
to 0, but the VMDq offset will contain the location of the first PF pool.

This change essentially makes it so that we can enable almost all of the
features all at once. This patch allows for the combination of SR-IOV,
DCB, and FCoE in the case of the x540. It also beefs up the SR-IOV by
adding support for RSS to the PF.
The testing matrix gets to be very complex for this patch as there are a
number of different features and subsets for queueing options. I tried to
narrow these down a bit by restricting the PF to only supporting 4TC DCB
when it is enabled in addition to SR-IOV.

Previously we would get a mailbox error and still process the message.
Instead we should exit on error.
In addition we should also be flushing the ACK of the message so that we

Recent addition of code to find already allocated VFs failed to take
account that systems with 2 or more multi-port SR-IOV capable controllers
might have already enabled VFs. Make sure that the VFs the function is
finding are actually subordinate to the particular instance of the adapter
that is looking for them and not subordinate to some device that has
previously enabled SR-IOV.
This bug exists in 3.2 stable as well as 3.3 release candidates.
