/* FM Port API * The FM uses a general module called "port" to represent a Tx port (MAC), * an Rx port (MAC). * The number of ports in an FM varies between SOCs. * The SW driver manages these ports as sub-modules of the FM,i.e. after an * FM is initialized, its ports may be initialized and operated upon. * The port is initialized aware of its type, but other functions on a port * may be indifferent to its type. When necessary, the driver verifies * coherence and returns error if applicable. * On initialization, user specifies the port type and it's index (relative * to the port's type) - always starting at 0.
