From d0ff7383a3164adff7072719717d574436ec1677 Mon Sep 17 00:00:00 2001 From: Naveen Gangadharan Date: Wed, 8 Feb 2012 17:51:36 -0800 Subject: ath6kl: Add unicast mgmt frame buffering PS buffering of unicast Action frames that are sent in a context of a BSS. In AP mode when the recepient station goes to powersave and PS_POLL flag is not set, we would buffer the frames. Send out unicast mgmt bufferred frame when PS_POLL is received. This fixes a bug in P2P GO behavior when sending a GO Discoverability Request to a client that is in sleep mode. kvalo: indentation fixes Signed-off-by: Thirumalai Pachamuthu Signed-off-by: Naveen Gangadharan Signed-off-by: Aarthi Thiruvengadam Signed-off-by: Kalle Valo --- drivers/net/wireless/ath/ath6kl/wmi.c | 37 ++++++++++++++++++++++++++++++----- 1 file changed, 32 insertions(+), 5 deletions(-) (limited to 'drivers/net/wireless/ath/ath6kl/wmi.c') diff --git a/drivers/net/wireless/ath/ath6kl/wmi.c b/drivers/net/wireless/ath/ath6kl/wmi.c index bbbe0a74d3c..fce29f7f2e5 100644 --- a/drivers/net/wireless/ath/ath6kl/wmi.c +++ b/drivers/net/wireless/ath/ath6kl/wmi.c @@ -3182,8 +3182,9 @@ int ath6kl_wmi_remain_on_chnl_cmd(struct wmi *wmi, u8 if_idx, u32 freq, u32 dur) * ath6kl_wmi_send_mgmt_cmd instead.
