32c1087460 ath6kl: Export beacon interval and DTIM period through STA info
Now that we allow the first Beacon frame after each connection to
be processed at the host, we can figure out the DTIM period and
expose it with Beacon interval through STA info BSS parameters
to user space.

551185ca0a ath6kl: Update BSS information after connection
Since we may end up using a dummy BSS entry when roaming, allow one Beacon
frame -based bssinfo from the current BSS to be processed prior to starting
to filter all bssinfo events. This allows cfg80211 BSS table to be filled
with proper data in the roaming case where the full Beacon data may not
have been present at the time of roamed event.

82e14f56f7 ath6kl: Remove unnecessary bssinfo event header conversion
There is no point in unconditionally converting the bssinfo header
to the old version since only the new header is being used and the
driver can as well read the values from it when needed. Leaving out
the conversion saves some extra memory copying.

In addition, use the calculated "rssi" value snr - 95 dBm to get the
proper value in cfg80211 BSS table (i.e., something that more or less
matches with the value used in STA info).

1aaa8c7469 ath6kl: Replace internal node table with cfg80211 BSS table
The internal node table in ath6kl was not really used for any useful
purpose. It was just used to collect scan results during a scan and then
provide them in a burst to cfg80211 at the completion of the scan. There
is no point in doing this since cfg80211 is perfectly capable of
maintaining the BSS table and the BSS inform messages are sent in
separate function calls anyway.

This provides more complete information in the cfg80211 BSS table since
this allows Beacon and Probe Response frames to be distinguished and IEs
from them reported separately.

01cac476a4 ath6kl: Fix BSS update on roaming
This fixes the BSS "update" just before the connected or roamed event.
The previous implementation was completely broken: it forced a hardcoded
signal strength and IEs from Association _Request_ frame instead of any
Beacon information. This broke various things, including PMKSA caching.

The current workaround for creating a dummy BSS entry before the roamed
event is not exactly ideal, but that is quite a bit better than the
previous state. As a future improvement, cfg80211 could potentially be
extended to allow this type of use or ath6kl could delay sending the
roamed event before receiving a BSS info event.

cfc301edfb ath6kl: fix busy loop in ath6kl_bmi_get_rx_lkahd()
Brent reported that ath6kl busy loops if firmware doesn't boot for some
reason (in this case he was using an older firmware which wasn't supported
by ath6kl).

Investigation revealed that this was even on purpose,
ath6kl_bmi_get_rx_lkahd() had a parameter to disable the timeout check,
which is extremely evil. I didn't find any reason why the timeout needs
to be disabled so I just removed the feature. The function already busyloops
a maximum of one second if it doesn't get an answer, even that's too long.
If something takes longer than that a more friendly approach is needed.

572e27c00c ath6kl: Fix AP mode connect event parsing and TIM updates
This cleans up the connect event parsing by defining a union in
struct wmi_connect_event to match with the three possible sets of
fields that the target uses depending on which type of connect
event is being indicated. In addition, two AP cases are now
separated from ath6kl_connect_event() so that correct field names
can be used to make it actually possible to understand what the
code is doing.

The bug hiding in the previous mess was in parsing the AID incorrectly
when processing the new station connecting event in AP mode. The fix
here for that is also fixing TIM updates for PS buffering to use the
correct AID.
