functional under Linux despite an average driver
Linux support is announced, and indeed, the card works..... once you find and install the driver (tn40xx) by hand, and set up a workaround to have it reinstalled at each kernel update (no DKMS support).
In terms of performance, once the MTU was raised to a good value, we reached about 9.8Gb/s on iperf tests, which is very good, especially for this price!
Oh, and the driver also doesn't seem to appreciate the multiple MTU changes: a change at boot time at 9000, it's fine, as soon as you start doing 2-3 tests, the driver (or the card?) doesn't react anymore. Not very reassuring on the quality of the driver, but not really problematic in daily use.......
With a good Linux driver, this card would have had its 5th star....
