fcoe: adds spma mode support
If we can find a type NETDEV_HW_ADDR_T_SAN mac address from the corresponding netdev for a fcoe interface then sets up added the fc->ctlr.spma flag and stores spma mode address in ctl_src_addr. In case the spma flag is set then:- 1. Adds spma mode MAC address in ctl_src_addr as secondary MAC address, the FLOGI for FIP and pre-FIP will go out using this address. 2. Cleans up stored spma MAC address in ctl_src_addr in fcoe_netdev_cleanup. 3. Sets up spma bit in fip_flags for FIP solicitations along with exiting FPMA bit setting. 4. Initialize the FLOGI FIP MAC descriptor to stored spma MAC address in ctl_src_addr. This is used as proposed FCoE MAC address from initiator along with both SPMA and FPMA bit set in FIP solicitation, in response the switch may grant any FPMA or SPMA mode MAC address to initiator. Removes FIP descriptor type checking against ELS type ELS_FLOGI in fcoe_ctlr_encaps to update a FIP MAC descriptor, instead now checks against FIP_DT_FLOGI. I've tested this with available FPMA-only FCoE switch but since data_src_addr is updated using same old code for both FPMA and SPMA modes with FIP or pre-FIP links, so added SPMA mode will work with SPMA-only switch also provided that switch grants a valid MAC address.
