* ray_cs: Add include guardsRasmus Villemoes2014-08-282-4/+6
| | | | | | | | | | | The files ray_cs.h and rayctl.h both contain two thirds of what appears to be an include guard using the macro name RAYLINK_H (both lack the #define). Since RAYLINK_H is not defined anywhere, the #ifndefs are confusing no-ops. Add proper include guards using different macro names.

* mwifiex: fix left_len calculation issueAmitkumar Karwar2014-08-281-1/+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.

* ath9k_htc: advertise support for TDLSCsaba Kiraly2014-08-281-0/+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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some copy engine structures are target specific and are uploaded to the device during init/configuration.

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

The other one is an unexpected (and non-maskable via device CSR) MSI fw indication interrupt during teardown. This could trigger the same problem as the first corner case.
