It has support for Ethtool ioctls. The patch is against 2.5.4.
This device has the same USB vendor/product code (0x0423/0x000a) as the
CATC NetMate device. However, even though this device is based on a CATC
board, the catc.c driver that comes with Linux does not work with this device
as it as a simpler device than the NetMate device. Unlike the NetMate,
it only appears to allow one packet at a time to be transmitted or received
to the device (the NetMate allows write combining to increase performance).
It also has fewer commands, no registers and no LED control.
NEW This patch adds a fix for the multicast hash code.
The code has also been better intergrated into the catc.c file
so it is a smaller patch. This patch is against 2.5.5.
Backport of the above patch to 2.4.
This code is now in 2.5.7.
