After a station is added to the kernel's structures, userspace
has to be able to retrieve statistics about that station, especially
whether the station was idle and how much bytes were transferred
to and from it. This adds the necessary code to nl80211.

This introduces key handling to cfg80211/nl80211. Default
and group keys can be added, changed and removed; sequence
counters for each key can be retrieved.

This statistics is shown factor dropped by transformation
at /proc/net/xfrm_stat for developer.
It is a counter designed from current transformation source code
and defined as linux private MIB.
See Documentation/networking/xfrm_proc.txt for the detail.

A few netfilter modules provide their own union of IPv4 and IPv6
address storage. Will unify that in this patch series.
(1/4): Rename union nf_conntrack_address to union nf_inet_addr and
move it to x_tables.h.

We need to use rcu_assign_pointer/rcu_dereference to avoid races.
Also remove an obsolete CONFIG_IP_NAT_NEEDED ifdef.

The combination of NAT and helpers may produce TCP sequence adjustments.
In failover setups, this information needs to be replicated in order to
achieve a successful recovery of mangled, related connections. This patch is
particularly useful for conntrackd, see:

Use compat types and compat iterators when dealing with compat entries for
clarity. This doesn't actually make a difference for ip_tables, but is
needed for ip6_tables and arp_tables.

Make xt_compat_match_from_user return an int to make it usable in the
*tables iterator macros and kill a now unnecessary wrapper function.

Introduce scan capabilities to WEXT so that userspace can do intelligent
things with scan behavior such as handling hidden SSIDs more gracefully.
If the driver reports a specific scan capability, the driver must
respect the options specified in the iw_scan_req structure when handling
the SIOCSIWSCAN call, unless it's mode or state does not allow it to do
so, in which case it must return an error.
This version switches to Dave Kilroy's suggestion of claiming unused
padding space for the scan_capa field.

Change IPV4 specific macros LOOPBACK MULTICAST LOCAL_MCAST BADCLASS
and ZERONET macros to inline functions ipv4_is_<type>(__be32 addr)
Adds type safety and arguably some readability.
Changes since last submission:
Removed ipv4_addr_octets function
Used hex constants
Converted recently added rfc3330 macros
