However, in our current implementation, the ice_aqc_opc_get_cee_dcb_cfg (0x0A07) AQ command doesn't provide a way to communicate the protocol port number to the AQ's caller. Thus, we assume that 3260 is the iSCSI port number at the AQ's caller layer. Rely on the dcbx-willing mode, desired QoS and remote QoS configuration to determine which port number that iSCSI will use.
