commit 1d5c92654b2ebd95bee4f2bc4690b883c468b1a4
Author: Damien Zammit <dam...@zamaudio.com>

rumpnet: Add device translator for (Intel) NICs
This adds a working rump driver for /dev/wmX cards,
which are Intel i8254x Gigabit Ethernet devices.
(See man.netbsd.org for "wm(4)")
This should be easily extended to support other NICs
by contributing some makefile foo to netbsd/rump.
TESTED:
- On UP+apic it works 100% with hurd-i386.
- On SMP it also works 100% with hurd-i386.
Example usage:
settrans -fgap /dev/rumpnet /hurd/rumpnet
settrans -fgap /dev/wm0 /hurd/devnode -M /dev/rumpnet wm0
settrans -fgap /servers/socket/2 /hurd/pfinet -i /dev/wm0
ifup /dev/wm0
TODO: check tcpdump support
Requires latest master of librump for nofifofs dynamic lib.
