FPMA indicates that the Fabric will provide the host's N_Port's MAC address. When sending a FLOGI/FDISC frame and FPMA was negotiated through FIP discovery we still need to provide the MAC descriptor, as per the specification, but the MAC should be zero'd out since the FCF will be providing it in the FLOGI/FDISC ACC. In FC-BB-5 section 7.8.7.4.2 (Fabric login) it states: The MAC address field in the MAC address descriptor of a FIP FLOGI Request operation or a FIP NPIV FDISC Request operation shall contain: a) the proposed MAC address to use as VN_Port MAC address if the ENode is requesting to use SPMA (see table 27); b) all zeroes to indicate no MAC address is proposed if the ENode is requesting to use FPMA (see table 27); or c) the proposed MAC address to use as VN_Port MAC address if the ENode supports both SPMA and FPMA and leaves the decision of which addressing scheme to use to the FCF (i.e., if both the FP and SP bits are set to one, see table 27). This patch fixes case B. This patch also adds debug statements to illustrate whether a FPMA or SPMA MAC is added to a FLOGI/FDISC frame.
