Sub policy is introduced. Main and sub policy are applied the same flow.
(Policy that current kernel uses is named as main.)
It is required another transformation policy management to keep IPsec
and Mobile IPv6 lives separate.
Policy which lives shorter time in kernel should be a sub i.e. normally
main is for IPsec and sub is for Mobile IPv6.
(Such usage as two IPsec policies on different database can be used, too.)
Limitation or TODOs:
- Sub policy is not supported for per socket one (it is always inserted as main).
- Current kernel makes cached outbound with flowi to skip searching database.
However this patch makes it disabled only when "two policies are used and
the first matched one is bypass case" because neither flowi nor bundle
information knows about transformation template size.

[IPV6] MIP6: Ignore to report if mobility headers is rejected.
Ignore to report user-space for known mobility headers rejected by
destination options header transformation.
Mobile IPv6 specification (RFC3775) says that mobility header
is used with destination options header carrying home address option
only for binding update message. Other type message cannot be used
and node must drop it silently (and must not send binding error) if
receving such packet.
To achieve it, (1) application should use transformation policy and
wild-card states to catch binding update message prior other packets
(2) kernel doesn't report the reject to user-space not to send
binding error message by application.
This patch is for (2).

For outbound transformation, bundle is checked whether it is
suitable for current flow to be reused or not. In such IPv6 case
as below, transformation may apply incorrect bundle for the flow instead
of creating another bundle:
- The policy selector has destination prefix length < 128
(Two or more addresses can be matched it)
- Its bundle holds dst entry of default route whose prefix length < 128
(Previous traffic was used such route as next hop)
- The policy and the bundle were used a transport mode state and
this time flow address is not matched the bundled state.
This issue is found by Mobile IPv6 usage to protect mobility signaling
by IPsec, but it is not a Mobile IPv6 specific.
This patch adds strict check to xfrm_bundle_ok() for each
state mode and address when prefix length is less than 128.

useful one(out of receive buffer/rwnd).
Also moved the SCTP MIB data structures from the generic include
directories to include/sctp/sctp.h.

[IPv6] route: FIB6 configuration using struct fib6_config
Replaces the struct in6_rtmsg based interface orignating from
the ioctl interface with a struct fib6_config based on. Allows
changing the interface without breaking the ioctl interface
and avoids passing on tons of parameters.
The recently introduced struct nl_info is used to pass on
netlink authorship information for notifications.

[PKT_SCHED]: Kill pkt_act.h inlining.
This was simply making templates of functions and mostly causing a lot
of code duplication in the classifier action modules.
We solve this more cleanly by having a common "struct tcf_common" that
hash worker functions contained once in act_api.c can work with.
Callers work with real action objects that have the common struct
plus their module specific struct members. You go from a common
object to the higher level one using a "to_foo()" macro which makes
use of container_of() to do the dirty work.
This also kills off act_generic.h which was only used by act_simple.c
and keeping it around was more work than the it's value.

[IPv4]: FIB configuration using struct fib_config
Introduces struct fib_config replacing the ugly struct kern_rta
prone to ordering issues. Avoids creating faked netlink messages
for auto generated routes or requests via ioctl.
A new interface net/nexthop.h is added to help navigate through
nexthop configuration arrays.
A new struct nl_info will be used to carry the necessary netlink
information to be used for notifications later on.
