This patch improves support for the device considerably. 1. The wifi didn't work in the initial release. This was because the WMAC of the AR9340 is not connected to the antennas. (However, it can pick up wifi signals, if they are strong enough!) Instead there's a dedicated AR9300 chip on the same board, which works. 2. Ethernet throughput is improved. iperf shows that the hardware can sustain more than 200Mbit/s and no longer drops any packages when the link is under load.
