This is new nfs code (including nfsv4) imported from FreeBSD. It is
not even experimental yet - you don't want to be mucking with it.

The nfs code (both nfs and nfsd) that NetBSD currently uses is in
sys/nfs.


The following things are here:

   client/          - nfs client code, from sys/fs/nfsclient in freebsd
   server/          - nfsd server code, from sys/fs/nfsserver in freebsd
   nlm/             - kernel-side nfs lock manager, from sys/nlm in freebsd
   common/          - shared common code, from
                              * sys/fs/nfs in freebsd
                              * sys/nfs in freebsd
   files.newnfs - config goo
   nfs2netbsd.sh - script for preparing a cvs import from a freebsd tree

The FreeBSD shared common code contained two (different) nfsproto.h
and xdr_subs.h files. This is how they've been imported:

   sys/fs/nfs/nfsproto.h      ->        common/nfsproto.h
   sys/fs/nfs/xdr_subs.h      ->        common/xdr_subs.h
   sys/nfs/nfsproto.h                   ->        common/oldnfsproto.h
   sys/nfs/xdr_subs.h                   ->        common/old_xdr_subs.h
