No, this is a hardware limitation. The 3Com design does not include Rx 
interrupt mitigation. The only solution is software, using something like 
the recently introduced NAPI; however, to use it efficiently the driver 
has to be modified and to my knowledge there is no such driver yet. It's 
on my list of things to add to the 3c59x driver, but recently this list 
just grows because I can't find time...
