My earlier patch,
"mac80211: unify config_interface and bss_info_changed"
introduced a bug in iwlwifi where it will do some things
incorrectly now when reassociating.
Revamp iwl_bss_info_changed to fix that issue and make it
easier to read. Also, while at it, add comments about things
that it should do but currently doesn't.
Finally, also improve the locking in the function.

The card firmware does not set the Command Download Ready interrupt bit
when IEEE PS mode is enabled, preventing the driver from sending
commands (such as the command to exit IEEE PS mode) since there is no
indication that the card is ready to accept commands.
This patch works around the problem by using the the TX Download Ready
bit in place of the Command Download Ready Bit while in IEEE PS mode.
TX Download Ready is set in IEEE PS mode.

It looks like some programs (e.g., NM) are setting an empty SSID with
SIOCSIWESSID in some cases. This seems to trigger mac80211 to try to
associate with an invalid configuration (wildcard SSID) which will
result in failing associations (or odd issues, potentially including
kernel panic with some drivers) if the AP were to actually accept this
anyway).
Only start association process if the SSID is actually set. This
speeds up connection with NM in number of cases and avoids sending out
broken association request frames.

While doing trie_rebalance(): resize(), inflate(), halve() RCU free
tnodes before updating their parents. It depends on RCU delaying the
real destruction, but if RCU readers start after call_rcu() and before
parent update they could access freed memory.
It is currently prevented with preempt_disable() on the update side,
but it's not safe, except maybe classic RCU, plus it conflicts with
memory allocations with GFP_KERNEL flag used from these functions.
This patch explicitly delays freeing of tnodes by adding them to the
list, which is flushed after the update is finished.

menuconfig IEEE802154_DRIVERS is a bool that depends on tristate IEEE802154.
If the IEEE802154 symbol is 'm', the bool becomes 'y'.
This allows tristate symbols under IEEE802154_DRIVERS to be configured as
'y' and cause build problems.
Changing the menuconfig bool to a tristate fixes this.
