Each FMan has several MACs, each implementing an Ethernet interface. Earlier
|
||
|
|
versions of FMan used the Datapath Three Speed Ethernet Controller (dTSEC) for
|
||
|
|
10/100/1000 MBit/s speeds, and the 10-Gigabit Ethernet Media Access Controller
|
||
|
|
(10GEC) for 10 Gbit/s speeds. Later versions of FMan use the Multirate
|
||
|
|
Ethernet Media Access Controller (mEMAC) to handle all speeds.
