So you now use remapping of mbufs instead of copying the data for the lance?
Wow, I like this :-)

workstations. I have modified the vsbus lance attachment to work with it
(as well with older VS31000/VS2000). (that's the buf 0x0-0xffff). This
is a prerequisite for getting SCSI support working.
The biggest problem is that interrupt probe for the VS4000 assumed that
the lance has a valid pointer to an init block. but since the sgmap was
nuked, there wasn't one. So now the probe routine provides one.

Not yet. The MI amd7990 doesn't support that. Jason and I have talked about
writing a second le driver that would do that.

I've been working on an if_pcn.c for the PCnet-PCI family... would be worked
into an if_ln.c for the LANCE probably (but I don't think it would be easily
sharable).
