Can't tell. Atheros' ethernet driver source is available
in the GPL source for this device (but I guess this is 
nothing special. Version is: s17_ssdk_v1.0.4p1).

I don't know if the rate limiting implementation you describe would
be possible to implement or not. But, the vendor driver has some 
code to setup some hardware rate limiting in "athrs_qos.c".
