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.
