From be41b052029f75a72df3c437a238bf9d574b6461 Mon Sep 17 00:00:00 2001 From: Mohammed Shafi Shajakhan Date: Mon, 8 Oct 2012 21:30:51 +0530 Subject: [PATCH] ath9k: Ensure we set FTP_STOMP_LOW weight when WLAN is idle When WLAN is idle ensure we downgrade to FTP_STOMP_LOW weight (from STOMP_LOW) to provide more bandwidth for BT FTP profile. WLAN's idleness can be estimated by taking into account of the rx data packets and just ignore beacons, qos nullfunc etc. Also update bt_wait_time even if the chip is in NETWORK SLEEP mode. This should help BT throughput when WLAN is idle. Signed-off-by: Mohammed Shafi Shajakhan Signed-off-by: John W.
