Subject: [PATCH] ath10k: add support to configure channel dwell time
|
|
|
|
Configure channel dwell time from duration of the scan request
|
|
received from mac80211 when the duration is non-zero. When the
|
|
scan request does not have duration value, use the default ones,
|
|
the current implementation.
|
|
|
|
Corresponding flag NL80211_EXT_FEATURE_SET_SCAN_DWELL is
|
|
advertized.
|
|
|
|
Supported Chipsets:
|
|
-QCA988X/QCA9887 PCI
|
|
-QCA99X0/QCA9984/QCA9888/QCA4019 PCI
|
|
-QCA6174/QCA9377 PCI/USB/SDIO
|
|
-WCN3990 SNOC
|
|
|
|
Tested on QCA9984 with firmware ver 10.4-3.6-0010
