ath9k_hw: do not lower ANI setting below default on AR913x
|
|
|
|
When the amount of noise fluctuates strongly, low immunity settings
|
|
can sometimes disrupt signal detection on AR913x chips. When that
|
|
happens, no OFDM/CCK errors are reported anymore, and ANI tunes the
|
|
radio to the lowest immunity settings.
|
|
Usually rx/tx fails as well in that case.
|
|
|
|
To fix this, keep noise immunity settings at or above ANI default level,
|
|
which will keep radio parameters at or above INI values.

mac80211: exclude AP_VLAN interfaces from tx power calculation
|
|
|
|
Their power value is initialized to zero. This patch fixes an issue
|
|
where the configured power drops to the minimum value when AP_VLAN
|
|
interfaces are created/removed.

ath9k: fix a scheduling while atomic bug in CSA handling
|
|
|
|
Commit "ath9k: prepare for multi-interface CSA support" added a call to
|
|
ieee80211_iterate_active_interfaces in atomic context (beacon tasklet),
|
|
which is crashing.
|
|
Use ieee80211_iterate_active_interfaces_atomic instead.

ath9k_hw: reduce ANI firstep range for older chips
|
|
|
|
Use 0-8 instead of 0-16, which is closer to the old implementation.
|
|
Also drop the overwrite of the firstep_low parameter to improve
|
|
stability.
