[IPSEC]: Kill obsolete get_mss function
Now that we've switched over to storing MTUs in the xfrm_dst entries, we no longer need the dst's get_mss methods. This patch gets rid of them. It also documents the fact that our MTU calculation is not optimal for ESP. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
