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).

The internal node table in ath6kl was not really used for any useful

maintaining the BSS table and the BSS inform messages are sent in

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

When 64-bit DMA was first used, there were problems with the

flag in the allocation of coherent ring descriptor memory.
The original problem is now believed to have been due to bugs in

those bugs have been fixed. Accordingly, the requirement for the
