Re: netbsd/amd64 5.1rc4 domU network

Hi,

I wrote a xenfront-copy patch for NetBSD DomU.

http://blog.yellowback.net/uploads/netbsd-5.99.27-xenfront-rx-copy.patch

Networking works in my environment:
  Xen: xen-4.0.2-rc1-pre (64bit)
  Dom0: Linux 2.6.32.21(pvops) (64bit) + Ubuntu 9.04
  DomU: NetBSD 5.99.39 (64bit)
