ipsec: Remove obsolete MAX_AH_AUTH_LEN
While tracking down the MAX_AH_AUTH_LEN crash in an old kernel I thought that this limit was rather arbitrary and we should just get rid of it. In fact it seems that we've already done all the work needed to remove it apart from actually removing it. This limit was there in order to limit stack usage. Since we've already switched over to allocating scratch space using kmalloc, there is no longer any need to limit the authentication length. This patch kills all references to it, including the BUG_ONs that led me here. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
