You don't have to do anything actually.  FreeBSD serves both NFSv2 and
NFSv3 clients by default:

$ rpcinfo -p | grep nfs
    100003    2   udp   2049  nfs
    100003    3   udp   2049  nfs
    100003    2   tcp   2049  nfs
    100003    3   tcp   2049  nfs

You can disable NFSv3 with the -2 option to mountd, but if you have to
do that, then your Linux distro is extremely broken and you should have
your vendor fix it.
