1 = 100Mbps operation
This bit setting is only applicable to MII and RMII modes.
Bits 0-2: Forwarding Mode Control (FMC[2:0])
000 = Reserved
In all forwarding modes, VCAT/LCAS can be used to aggregate multiple physical serial ports for each WAN
Group’s data stream, except on devices that do not support VCAT/LCAS.

directions. In this mode, Ethernet frames from both ports can be forwarded by VLAN tag to two
shared WAN groups. Within each WAN group, there are two sets of four priority queues. The two
sets of priority queues are serviced with a round-robin algorithm. Frames received from the WAN
side can be forwarded by VLAN tag to either Ethernet port. The LAN-to-WAN and WAN-to-LAN
mappings are independent and can be configured separately.
