When an exchange is received with a FIP encapsulation, we need to know that the response must be sent via FIP and what the original ELS opcode was. This becomes important for VN2VN mode, where we may receive FLOGI or LOGO from several peer VN_ports, and the LS_ACC or LS_RJT must be sent FIP-encapsulated with the correct sub-type. Add a field to the struct fc_frame, fr_encaps, to indicate the encapsulation values. That term is chosen to be neutral and LLD-agnostic in case non-FCoE/FIP LLDs might find it useful. The frame fr_encaps is transferred from the ingress frame to the exchange by fc_exch_recv_req(), and back to the outgoing frame by fc_seq_send(). This is taking the last byte in the skb->cb array. If needed, we could combine the info in sof, eof, flags, and encaps together into one field, but it'd be better to do that if and when its needed.
