Default Description
Speed
0, 10, 100, 1000
0
Speed forces the line speed to the
specifi ed value in megabits per
second (Mbps). If this parameter is
not specifi ed or is set to 0 and the
link partner is set to auto-negoti-
ate, the board will auto-detect the
correct speed. Duplex must also be
set when Speed is set to either 10
or 100.
This parameter is supported only on
adapters using copper connections.
TxDescrip-
tors
80-256 for 82542
and 82543-based
adapters
80-4096 for all
other supported
adapters
256
This value is the number of transmit
descriptors allocated by the driver.
Increasing this value allows the
driver to queue more transmits. Each
descriptor is 16 bytes.
TxIntDelay
0-65535 (0=off)
64
This value delays the generation of
transmit interrupts in units of 1.024
microseconds. Transmit interrupt re-
duction can improve CPU effi ciency
if properly tuned for specifi c network
traffi c. If the system is reporting
dropped transmits, this value may be
set too high causing the driver to run
out of available transmit descriptors.
