/* 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. |
