    scsi: qedf: Use granted MAC from the FCF for the FCoE source address if it is available. · a3cd42a9
    Chad Dupuis authored
    Currently in the driver we've been using the fc_fcoe_set_mac() function to
    set the source MAC for FCoE traffic.  This works well in most cases as it
    uses the spec. default FCF-MAC.  However, if the administrator changes the
    FCF-MAC switch, then any FCoE traffic we send will be dropped by the
    switch.
    
    Instead we should check the granted MAC from the FLOGI payload and use that
    address if it is present.  Otherwise, fall back to using the the default
    FCF-MAC and the fabric ID of the port as the FCoE MAC address.
    
    Once this address is known we need to set it when doing non-offload
    traffic, offload traffic and setting the data_src_address libfcoe uses for
    FIP keep alive messages.
