Fix last_sample initialization. kzalloc'ing the per-STA data wasn't enough,
as jiffies can assume negative values as well. This fixes a bug which
prevented correct PID operation for a while after booting.
Thanks to Michael Buesch for reporting this.

Commit c7a51bda ("mac80211: restructure __ieee80211_rx") extracted
__ieee80211_rx_handle_packet out of __ieee80211_rx and hence changed
the locking rules for __ieee80211_rx_handle_packet(), it is now
invoked under RCU lock. There is, however, one instance left where
it contains an rcu_read_unlock() in an error path, which is a bug.

This patch assigns correct TID to frames transmitted between
two stations in the same BSS in AP mode.
The problem is that skb->protocol is not set to ETH_P_IP and it is wrong
to use that field at this stage.
The fix compares the LLC/Protocol headers explicitly to check if the
encapsulated frame is IP frame

On x86_64, sizeof(struct rtable) is 0x148, which is rounded up to
0x180 bytes by SLAB allocator.
We can reduce this to exactly 0x140 bytes, without alignment overhead,
and store 12 struct rtable per PAGE instead of 10.
rate_tokens is currently defined as an "unsigned long", while its
content should not exceed 6*HZ. It can safely be converted to an
unsigned int.
Moving tclassid right after rate_tokens to fill the 4 bytes hole
permits to save 8 bytes on 'struct dst_entry', which finally permits
to save 8 bytes on 'struct rtable'

On namespace start we mainly prepare the ctl variables.
When the namespace is stopped we have to kill all the fragments that
point to this namespace. The inet_frags_exit_net() handles it.

The inet_frags.lru_list is used for evicting only, so we have
to make it per-namespace, to evict only those fragments, who's
namespace exceeded its high threshold, but not the whole hash.
Besides, this helps to avoid long loops in evictor.
The spinlock is not per-namespace because it protects the
hash table as well, which is global.

Since we have one hashtable to lookup the fragment, having
different secret_interval-s for hash rebuild doesn't make
sense, so move this one to inet_frags.
The inet_frags_ctl becomes empty after this, so remove it.
The appropriate ctl table is kept read-only in namespaces.

Since fragment management code is consolidated, we cannot have the
pointer from inet_frag_queue to struct net, since we must know what
king of fragment this is.
So, I introduce the netns_frags structure. This one is currently
empty, but will be eventually filled with per-namespace
attributes. Each inet_frag_queue is tagged with this one.
The conntrack_reasm is not "netns-izated", so it has one static
netns_frags instance to keep working in init namespace.

This is a preparation for sysctl netns-ization.
Move the ctl tables to the files, where the tuning
variables reside. Plus make the helpers to register
the tables.
This will simplify the later patches and will keep
similar things closer to each other.
ipv4, ipv6 and conntrack_reasm are patched differently,
but the result is all the tables are in appropriate files.

Before calling update_beacon() mac80211 must
initialize the control.vif pointer so it can
be used by the driver to determine which
interface is trying to send the beacon.
v2: ieee80211_beacon_get() should also initialize the
vif pointer since it can be called by mac80211 internally
before calling config_interface().

This patch (based on Ron Rindjunsky's) creates a framework for
a unified way to pass BSS configuration to drivers that require
the information, e.g. for implementing power save mode.
This patch introduces new ieee80211_bss_conf structure that is
passed to the driver via the new bss_info_changed() callback
when the BSS configuration changes.
This new BSS configuration infrastructure adds the following
new features:
* drivers are notified of their association AID
* drivers are notified of association status
and replaces the erp_ie_changed() callback. The patch also does
the relevant driver updates for the latter change.

This patch gets rid of the if_id stuff where possible in favour of
a new per-virtual-interface structure "struct ieee80211_vif". This
structure is located at the end of the per-interface structure and
contains a variable length driver-use data area.
This has two advantages:
* removes the need to look up interfaces by if_id, this is better
for working with network namespaces and performance
* allows drivers to store and retrieve per-interface data without
having to allocate own lists/hash tables
