2014-08-28mwifiex: use firmware API revision from GET_HW_SPEC responseAmitkumar Karwar2-1/+8
Newer firmware returns API revision in GET_HW_SPEC command response. We will make use of it instead of parsing this information from FW release number.

2014-08-28mwifiex: fix left_len calculation issueAmitkumar Karwar1-1/+2
While updating 'left_len' in each iteration, we should subtract last TLV length not the accumulated length of TLVs parsed till now. This bug in parsing logic is exposed by newer firmware which adds two TLVs in GET_HW_SPEC command response. Earlier firmwares used to add only one TLV.

2014-08-28ath9k_htc: advertise support for TDLSCsaba Kiraly1-0/+2
Based on a quick test with AR9271, TDLS seems to be working fine. Tests were done with 2 Atheros AR9271 based devices with firmware 1.3 (sha1 8d49f928aa40ac53c729189bff1333cd373a7fb5), associated with a WAP54G access point. TDLS worked fine both in WPA2 mode and without encryption. Stations maintained ping flood traffic between each other and towards the AP without significant losses. Not tested with AR7010. TDLS was enabled in earlier patches the same way for other Atheros drivers: ath9k (fd6562344dea2b8b2a5d644cf971f4e56004500a), and carl9170 (d1f3de71a584a82ee4e84505fce9acccf40215ff).

Broadcom hardware supports auto-adjustment of TX power depending on the currently used rate. So far all calculations were handled without any helpers (API) using big arrays and magic offsets.

This fixes two corner cases. One is a race between disabling copy engine interrupts and unhandled pending interrupts on the host.
