idev has been stored on seq->private. NULL has been stored for global
statistics.
The situation is changed with net namespace. We need to store pointer to
struct net and the only place is seq->private. So, we'll have for
/proc/net/dev_snmp6/* and for /proc/net/snmp6 pointers of two different
types stored in the same field.
This effectively requires to separate seq_ops of these files.

It all started from me noticing that this urgent check in
tcp_clean_rtx_queue is unnecessarily inside the loop. Then
I took a longer look to it and found out that the users of
urg_mode can trivially do without, well almost, there was
one gotcha.
Bonus: those funny people who use urg with >= 2^31 write_seq -
snd_una could now rejoice too (that's the only purpose for the
between being there, otherwise a simple compare would have done
the thing). Not that I assume that the rest of the tcp code
happily lives with such mind-boggling numbers :-). Alas, it
turned out to be impossible to set wmem to such numbers anyway,
yes I really tried a big sendfile after setting some wmem but
nothing happened :-). ...Tcp_wmem is int and so is sk_sndbuf...
So I hacked a bit variable to long and found out that it seems
to work... :-)

The association response IEs are sent to userland with an IWEVCUSTOM
event, which unfortunately is limited to a little more than 100 bytes
of IE information with the encoding used. Many APs send so much
IE information that this message overflows. When the IWEVCUSTOM
event is too large, the kernel doesn't send it to userland anyway --
better just not to send it.
An attempt was made by Jouni Malinen to correct this issue by
converting to use IWEVASSOCREQIE and IWEVASSOCRESPIE messages instead
("mac80211: Use IWEVASSOCREQIE instead of IWEVCUSTOM"). Unfortunately,
that caused a problem due to 32-/64-bit interactions on some systems and
was reverted after the 'userland ABI' rule was invoked. That leaves
us with this option instead of a proper fix, at least until we move
to a cfg80211-based solution.

The LED state was not being updated by rfkill_force_state(), which
will cause regressions in wireless drivers that had old-style rfkill
support and are updated to use rfkill_force_state().
The LED state was not being updated when a change was detected through
the rfkill->get_state() hook, either.
Move the LED trigger update calls into notify_rfkill_state_change(),
where it should have been in the first place. This takes care of both
issues above.

- This patch (against the linux-wireless-next git tree) removes a
redundant check in ieee80211_master_start_xmit (net/mac80211/tx.c)
and adjust indentation in this method accordingly.
In this method, there is no need to call again the
ieee80211_is_data() method; this is checked immediately before, in the
"if" command (we will not enter this block unless ieee80211_is_data()
is true, so that the "and" (&&) condition in that "if" command will be
fullfilled ).

This enables Adaptive Noise Immunity (ANI) on ath9k.
ANI is as algorithm designed to minimize the detrimental
effects of time-varying interferences. This should
help with throughput in noisy environments. To use
ANI we re-enable the MIB interrupt. Since ANI works
on a timer and updates the noise floor we take
advantage of this and also report a non-static noise
floor now to mac80211.
