improper value can result in driver performance
degradation or failure.

fdr_filter
Full-Duplex Repeater Filter. For older adapters

attached to a Full-Duplex Repeater. Use a value of
0 for off, or 1 for on. The default is 0 (off).
rx_flow_control
If link negotiation is on, a value of 1 allows the
adapter to negotiate 802.3x receive flow control
with the device at the other end of the link. If
802.3x flow control is supported by the other
device, receive pause packets will be respected. A
value of 0 disables receive flow control. The default
is 1 (on).
