#  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 "force_speed_duplex" module parameter can be used set the
#  interface speed and duplex of the ethernet controller.  The
#  following values are supported:
#   force_speed_duplex=0 - autonegotiate
#   force_speed_duplex=1 - 10Mbps half duplex
#   force_speed_duplex=2 - 10Mbps full duplex
#   force_speed_duplex=3 - 100Mbps half duplex
#   force_speed_duplex=4 - 100Mbps full duplex
#   force_speed_duplex=5 - autonegotiate for 10Mbps half duplex
#   force_speed_duplex=6 - autonegotiate for 10Mbps full duplex
#   force_speed_duplex=7 - autonegotiate for 100Mbps half duplex
#   force_speed_duplex=8 - autonegotiate for 100Mbps full duplex
#   force_speed_duplex=9 - autonegotiate for 1000Mbps full duplex
