Addrtype match has a new revision (1), which lets address type checking
limited to the interface the current packet belongs to. Either incoming
or outgoing interface can be used depending on the current hook. In the
FORWARD hook two maches should be used if both interfaces have to be checked.
The new structure is ipt_addrtype_info_v1.

Revision 0 lets older userspace programs use the match as earlier.
ipt_addrtype_info is used.

We're not multiplying the size with the number of CPUs anymore, so the

Instead of using a big array of NR_CPUS entries, we can compute the size
needed at runtime, using nr_cpu_ids

This should save some ram (especially on David's machines where NR_CPUS=4096 :
32 KB can be saved per table, and 64KB for dynamically allocated ones (because
of slab/slub alignements) )

In particular, the 'bootstrap' tables are not any more static (in data
section) but on stack as their size is now very small.

This also should reduce the size used on stack in compat functions
(get_info() declares an automatic variable, that could be bigger than kernel
stack size for big NR_CPUS)

When merging the input paths of IPsec I accidentally left a hard-coded
AF_INET for the state lookup call.  This broke IPv6 obviously.  This
patch fixes by getting the input callers to specify the family through
skb->cb.

This looks very much like the patch for ipv4's devinet.

This is also intended to help us with the net namespaces
and saves the ipv6.ko size by ~320 bytes.

The difference from the first version is just the patch
offsets, that changed due to changes in the patch #2.

Currently this call is (ab)used similar to devinet one - it
registers sysctls for devices and for the "default" confs, while
the "all" sysctls are registered separately. But unlike its
devinet brother, the passed inet6_device is needed.

The fix is to make a __addrconf_sysctl_register(), which registers
sysctls for all "devices" we need, including "default" and "all" :)

The original addrconf_sysctl_register() calls the introduced
function, passing the inet6_device, device name and ifindex (to
be used as procname and ctl_name) into it.

Thanks to Herbert again for pointing out, that we can shrink the
argument list to 1 :)

This looks very much like the patch for neighbors.

The path is also located on the stack and is prepared
inside the function. This time, the call to the registering
function is guarded with the RTNL lock, but I decided
to keep it on the stack not to litter the devinet.c file
with unneeded names and to make it look similar to the
neighbors code.

This is also intended to help us with the net namespaces
and saves the vmlinux size as well - this time by more
than 670 bytes.

The difference from the first version is just the patch
offsets, that changed due to changes in the patch #2.

Currently this call is used to register sysctls for devices
and for the "default" confs. The "all" sysctls are registered
separately.

Besides, the inet_device is passed to this function, but it is
not needed there at all - just the device name and ifindex are
required.

Thanks to Herbert, who noticed, that this call doesn't even
require the devconf pointer (the last argument) - all we need
we can take from the in_device itself.

The fix is to make a __devinet_sysctl_register(), which registers
sysctls for all "devices" we need, including "default" and "all" :)

The original devinet_sysctl_register() works with struct net_device,
not the inet_device, and calls the introduced function, passing
the device name and ifindex (to be used as procname and ctl_name)
into it.
