nfp: bpf: support setting the RX queue index BPF has access to all internal FW datapath structures. Including the structure containing RX queue selection. With little coordination with the datapath we can let the offloaded BPF select the RX queue. We just need a way to tell the datapath that queue selection has already been done and it shouldn't overwrite it. Define a bit to tell datapath BPF already selected a queue (QSEL_SET), if the selected queue is not enabled (>= number of enabled queues) datapath will perform normal RSS. BPF queue selection on the NIC can be used to replace standard datapath RSS with fully programmable BPF/XDP RSS.
