IBM Processor for Network Resources
Preliminary
Packet Routed LCD
Packet Routed LCD Packed and Miscellaneous Field Layouts
A packet routed LCD allows packets to be received from the POS-PHY. Once received, the packet buffer is
then routed internally to the scheduler and rescheduled for transmission. Normally, when a packet is
received, the receive LCD address is written into the packet header and the buffer is surfaced to the user.
When a packet is routed, the routedLcd field is used to fill in the LCD address in the packet header. This
allows packets to be routed out the transmit interface with the same or different LCD.
The low order bits in the routedLcd field should be set correctly to free the buffer on transmit. These bits cor-
respond to the flag bits in the packet header.
This is also called forwarded or fast forward mode.
