Added code to support Tx/Rx from a VF representor port. The VF-reps use the RX/TX rings of the Trusted VF/PF. For each VF-rep, the Trusted VF/PF driver issues a VFR_ALLOC FW cmd that returns "cfa_code" and "cfa_action" values. The FW sets up the filter tables in such a way that VF traffic by default (in absence of other rules) gets punted to the parent function i.e. either the Trusted VF or the PF. The cfa_code value in the RX-compl informs the driver of the source VF. For traffic being transmitted from the VF-rep, the TX BD is tagged with a cfa_action value that informs the HW to punt it to the corresponding VF.
