Is there another driver that does this that I might look off of? With the
ep93xx I do have the ability to mask out Tx interrupts. Any other
ethernet performance tricks? Is there any way I can make the mbuf data
area 32bit aligned? I haven't profiled for that, but I'm sure that
m_copy() has just got to kill performance on the small packets. I would
really like to beat Linux 2.4 on this board.
