|
* ipg_delay is the number of usecs in addition to the 802.3 inter-
|
|
* packet gap. Turning on causes MAC layer behavior to change
|
|
* w/ respect to the carrier transmission after deferal periods;
|
|
* when on, it will violate the 802.3 spec by checking for carrier
|
|
* after the IPG + delay on prior deferred packets. Default is
|
|
* OFF (0)
|
|
ec_ipg_delay 0 0 24
|
|
|
|
* xpg_delay when on will prevent streaming of packets interleaved
|
|
* by the minimum 9.6us IPG. When > 0, each packet transmission
|
|
* will be seperated by the machine's interrupt latency + the delay
|
|
* in usecs specified. Default is OFF (0)

|
|
|
* 16coll_retry is the number of successive times that the driver
|
|
* will attempt to retransmit a packet that could not get through
|
|
* the interface because of experiencing 16 consecutive collisions.
|
|
* Beyond this limit, the packet will be dropped and higher protocol
|
|
* layers are responsible for retransmitting.
