2014-08-28mwifiex: rename macro and variables related to API revisionAmitkumar Karwar
We will remove 'fw' prefix from these variable and macro names and make them generic. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Avinash Patil <patila@marvell.com> Signed-off-by: Cathy Luo <cluo@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-08-28mwifiex: fix left_len calculation issueAmitkumar Karwar
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 Kiraly
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. It seems Broadcom recently decided to clean this up by developing PPR. Their wlc_ppr.h can be found in open parts of the SDK.
