iwlwifi: restore PAN support

in iwlwifi: move setting up fw parameters

Meenakshi moved code up to configure the transport layer, but this
code read the sku before it was set (from the EEPROM). This killed
P2P.
Only the ucode_flags are needed to configure the transport layer, not
the sku which _must_ be set after the EEPROM is read.

We need to reconfigure the transport in case the EEPROM disabled PAN
support. This is not the nicest thing to do, but we have no choice.
Document that we are allowed to configure the transport several times
before start_fw, but not after.

iwlwifi: redesign PASSIVE_NO_RX workaround

The PASSIVE_NO_RX workaround currently crosses
through the op_mode and transport layers, which
is a bit odd. This also isn't necessary, if the
transport simply reports when queues are full
(or no longer full) the op_mode can keep track
of this state, and report to mac80211 only what
*it* thinks is appropriate. What is appropriate
can then be based on whether queues should be
stopped to wait for RX or not.

This significantly simplifies the transport API,
it no longer needs to expose anything to stop a
queue, nor to wake "any" queue, this can all be
handled in the upper layer completely.

Also simplify the handling to not be dependent
on the context, that makes little sense as the
queues are shared and both contexts have to be
on the same channel anyway.

tcp: md5: correct a RCU lockdep splat

commit a8afca0329 (tcp: md5: protects md5sig_info with RCU) added a
lockdep splat in tcp_md5_do_lookup() in case a timer fires a tcp
retransmit.

At this point, socket lock is owned by the sofirq handler, not the user,
so we should adjust a bit the lockdep condition, as we dont hold
rcu_read_lock().

store the firmware. Split this out into
a separate file, iwl-fw.h, and make all
other code use it. To do this, also move

knowledge of "nic" from everything.

Now the op_mode has a fw pointer, and
(unfortunately) for now the shared data
also needs to keep one for the transport
to access dump the error log -- I think
that will move later.

Since I wanted to constify the firmware
pointers, some more changes were needed.

ath9k: fix signal strength reporting issues

not for reporting to mac80211.
This patch changes the code to calculate the signal strength from the rssi
directly instead of taking the average value, and flag everything but
the last subframe in an A-MPDU to tell mac80211 to ignore the signal strength
entirely, fixing signal strength fluctuation issues reported by various
users.
