Well there are multiple possibilities, the following may give some ideas:

Personally, I use " root=/dev/nfs rw nfsroot=<IP>:<DIR>,wsize=1500,rsize=1500" where "<IP>" is the NFS server IP address, "<DIR>" is the directory on the NFS server to mount as the rootfs.  Limiting wsize/rsize to 1500 helps to keep UDP fragmentation to a minimum.
