Not really. 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.
