The FIP code in libfcoe needed several changes to support NPIV 1) dst_src_addr needs to be managed per-n_port-ID for FPMA fabrics with NPIV enabled. Managing the MAC address is now handled in fcoe, with some slight changes to update_mac() and a new get_src_addr() function pointer. 2) The libfc elsct_send() hook is used to setup FCoE specific response handlers for FIP encapsulated ELS exchanges. This lets the FCoE specific handling know which VN_Port the exchange is for, and doesn't require tracking OX_IDs. It might be possible to roll back to the full FIP frame in these, but for now I've just stashed the contents of the MAC address descriptor in the skb context block for later use. Also, because fcoe_elsct_send() just passes control on to fc_elsct_send(), all transmits still come through the normal frame_send() path. 3) The NPIV changes added a mutex hold in the keep alive sending, the lport mutex is protecting the vport list. We can't take a mutex from a timer, so move the FIP keep alive logic to the link work struct.
