The ie(4) driver originates from the old 4.4BSD days. It drives the
i82596 found in hp700 machines in i82586 compatibility mode. The i82586
is a quite painfull chip, unable to do 32 bit or scatter gather DMA and
has other limitations. Race conditions are quite common in the ie(4)
driver due to the hardware, so you can ignore those errors. 

I wrote a new i82596 driver from scratch for NetBSD. This iee(4) driver
features 32 bit scatter gather DMA, vlan(4) support etc. and runs better
on non-LC PA7100 machines. I think I'll port it to OpenBSD. But first I
have to anon-cvs the OpenBSD source and all I have at home is modem dial
up...
