net/bnxt: add port representor infrastructure Defines data structures and code to init/uninit VF representors during pci_probe and pci_remove respectively. Most of the dev_ops for the VF representor are just stubs for now and will be will be filled out in next patch. To create a representor using testpmd: testpmd -c 0xff -wB:D.F,representor=1 -- -i testpmd -c 0xff -w05:02.0,representor=[1] -- -i To create a representor using ovs-dpdk: 1. First add the trusted VF port to a bridge ovs-vsctl add-port ovsbr0 vf_rep1 -- set Interface vf_rep1 type=dpdk options:dpdk-devargs=0000:06:02.0 2.

net/bnxt: support port representor data path 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.
