[IPSEC]: Rename mode to outer_mode and add inner_mode
This patch adds a new field to xfrm states called inner_mode. The existing mode object is renamed to outer_mode. This is the first part of an attempt to fix inter-family transforms. As it is we always use the outer family when determining which mode to use. As a result we may end up shoving IPv4 packets into netfilter6 and vice versa. What we really want is to use the inner family for the first part of outbound processing and the outer family for the second part. For inbound processing we'd use the opposite pairing. I've also added a check to prevent silly combinations such as transport mode with inter-family transforms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
