[PATCH] USB: ax8817x.c - Fix flags to greatly increase rx performance
The attached patch fixes the flags used on the receive URBs and greatly
increases throughput (especially on EHCI). On EHCI before the patch,
receives came in around 460KB/s and after I am in the 10-11MB/s range
which is about the same speed I am able to achieve using my Intel nics.
Now transmit is actually the bottleneck on EHCI (only getting around 6MB/s).
