ath: optimize processing of CTLs for country IEs for world roaming cards

2011-12-13T20:30:59Z

When we receive a country IE hint and we have a world roaming card we can optimize output power further by ensuring that we use the calibrated data for the country by using that country's own CTL data. That is -- when world roaming and when we process a country IE we no longer need to use the lowest output power of all CTLs instead we use an optimized CTL output power for that specific country. We accomplish this by copying the regulatory data prior on init and restoring it when cfg80211 tells us it gets a core hint. Core hints are only sent on init and when it wants to restore reguulatory settings. We take advantage of this fact and apply the cached regulatory data when we get a core hint. When we get a country IE hint though we process the regulatory data as if programmed for a specific country. Tested-by: Rajkumar Manoharan Signed-off-by: Luis R. Rodriguez Acked-by: Luis R.

ath: add a helper for processing reg data on init

2011-12-13T20:30:55Z

This has no functional change. The helper can be used later for other things like country IE changes and following the CTL for different countries. Signed-off-by: Luis R. Rodriguez Acked-by: Luis R. Rodriguez Signed-off-by: John W. Linville

ath: Fix NULL ptr dereference in ath_reg_apply_world_flags

2011-11-08T20:02:45Z

This happens with devices using a regulatory domain 0x68 that are only 5Ghz capable because ath_reg_apply_active_scan_flags assumes that we always have a 2,4Ghz band.

drivers/net: Add export.h to files using EXPORT_SYMBOL/THIS_MODULE

Signed-off-by: Paul Gortmaker drivers/net: Add export.h to wireless/brcm80211/brcmfmac/bcmsdh.c This relatively recently added file uses EXPORT_SYMBOL and hence needs export.h included so that it is compatible with the module.h split up work.

ath: fix 0x6C for beaconing/passive scan flags based on country IE

2011-04-19T19:38:02Z

The 0x6C regulatory domain is just like the 0x6A regulatory domain but differs in that 0x6C will allow adhoc and active scan on its channels only if we are associated to an AP with a country IE that allows those channels. The ath_reg_apply_beaconing_flags() does just this -- we respect the manufacturer's intent on only enabling beaconing modes of operation if and only if blessed by the country IE.
