Subject: [PATCH] ath: use CTL region from cfg80211 if unset in EEPROM
|
||
|
|
||
|
Many AP devices do not have the proper regulatory domain programmed in
|
||
|
EEPROM. Instead they expect the software to set the appropriate region.
|
||
|
For these devices, the country code defaults to US, and the driver uses
|
||
|
the US CTL tables as well.
|
||
|
On devices bought in Europe this can lead to tx power being set too high
|
||
|
on the band edges, even if the cfg80211 regdomain is set correctly.
|
||
|
Fix this issue by taking into account the DFS region, but only when the
|
||
|
EEPROM regdomain is set to default.
|
||
|
