mac80211: check IEEE80211_HW_QUEUE_CONTROL in ieee80211_check_queues()

Commit 3a25a8c8 (mac80211: add improved HW queue control) introduced a
bug when running in AP mode without the IEEE80211_HW_QUEUE_CONTROL
flag set.  The ieee80211_check_queues() function always returns
-EINVAL, preventing AP mode from starting.  To fix this, check whether
this flag is set before checking if cab_queue is set properly.

cfg80211: enforce lack of interface combinations

My grand plan to allow drivers to gradually move over
to advertising virtual interface combinations and only
enforce with drivers that do want it enforced doesn't
seem to be working out, only Christian ever added the
advertising (to carl9170), nobody else did.

Begin enforcing combinations in cfg80211 so that users
can rely on the information reported about a device.

brcm80211: smac: only provide valid regulatory hint

The driver provides a regulatory hint to cfg80211 as obtained from the
SPROM. Mostly, this will be a two-letter ISO country code. However, it
may obtain special country code similar to the world regulatory domain
as used in cfg80211. This patch avoids setting these special codes as
the hint is lost to cfg80211.

NFC: The core part should generate the target index

The target index can be used by userspace to uniquely identify a target
and thus should be kept unique, per NFC adapter. Moreover, some protocols
do not provide a logical index when discovering new targets, so we have to
generate one for them.
For NCI or pn533 to fetch their logical index, we added a logical_idx field
to the target structure.

iwlwifi: move eeprom into priv

The whole code around eeprom is distributed
across whole bunch of different files, most
of which belong to the to-be-DVM code. As a
result, it is currently very hard to split
out the EEPROM code to be generic. However,
it is also quite unlikely that the current
EEPROM code will be needed by the MVM code
as that has different mechanisms to query
the EEPROM (it does so through the uCode.)

So, at least temporarily, move everything
into priv. If it becomes necessary to use
the code from MVM, we will have to split it
out, but then it's also easier since we'll
know what pieces we need.

iwlwifi: move queue watchdog into transport

This removes one of the two sources of device
restarts in the upper layer -- those are a bit
inconvenient because normal restarts originate
in the transport. By moving the watchdog down
it can be treated the same.

Also rewrite the watchdog logic. Timers are
much more efficient when they never fire, so
instead firing a timer every 500ms set up a
timer for each TX queue and fire it only when
the queue is really stuck. This avoids the CPU
waking up when everything is working well.

While at it, remove the wd_disable config item
and replace it by simply setting wd_timeout to
IWL_WATCHHDOG_DISABLED (0).
