The card works all right with my latest development driver (not yet in 2.4.x), but *only* in half-duplex mode. We don't have enough information to make full-duplex work correctly. The card also has a rather suboptimal design. It accepts only 32-bit aligned buffers for Tx, which forces the driver to memcpy all the Tx packets into new (and properly aligned) buffers. So, basically, avoid this card if you have a choice. Ion -- It is better to keep your mouth shut and be thought a fool, than to open it and remove all doubt.
