Appendix B Configuring the Quad FastEthernet Device Driver Parameters 25
Defining the Current Status
The read-only parameters described in TABLE B-2 explain the operational mode of the
interface. These parameters define the current status.
Inter-Packet Gap Parameters
The PCI Fast Ethernet and Expansion (PFEX) ASIC supports the programmable
Inter-Packet Gap (IPG) parameters
ipg1 and ipg2 . The total IPG is the sum of ipg1
and ipg2 . The total IPG is 9.6 microseconds when the link speed set, by the auto-
negotiation protocol, is 10 Mbps. When the link speed is 100 Mbps, the total IPG is
0.96 microseconds.

instance Read and write Device instance
lance_mode Read and write Additional delay before transmitting
a packet
ipg0 Read and write Additional delay before transmitting
a packet
