ixgbe: Add support for SR-IOV w/ DCB or RSS

Browse source

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.
