#  The nForce network driver supports two optimization modes:
#   optimization=0 ; Throughput optimization
#   optimization=1 ; CPU optimization
#  CPU optimization mode ruduces the CPU utilization by using
#  interrupt moderation. Throughput optimization mode maximizes
#  the throughput.  This mode has higher CPU consumption.
#  By default, the driver runs in throughput optimization mode.

#  The "speed" module parameter can be used set the interface
#  speed of the ethernet controller.  By default the controller
#  will autosense the interface speed, but also supports the
#  following values:
#     speed=0 ; auto
#     speed=1 ; 10Mbps
#     speed=2 ; 100Mpbs

#  The "duplex" module parameter can be used to specify the
#  interface duplex.  By default the controller will autoselect
#  duplex, but also supports the following values:
#     duplex=0 ; auto
#     duplex=1 ; half duplex
#     duplex=2 ; full duplex
