+Rx Descriptors:
+ Number of receive descriptors. A receive descriptor is a data
structure that describes a receive buffer and its attributes to the network
controller. The data in the descriptor is used by the controller to write
data from the controller to host memory. In the 3.x.x driver the valid range
for this parameter is 64-256. The default value is 256. This parameter can be
changed using the command::
- ethtool -G eth? rx n

NOTE: setting the speed/duplex to incorrect values will cause the link to
