From 2e8180d84ba8c682dacbe6eba26c2279aa49eb0c Mon Sep 17 00:00:00 2001 From: Sreelakshmi Konamki Date: Tue, 12 Jul 2016 15:09:08 +0530 Subject: [PATCH] qcacld-3.0: Remove 11P channels from channel list in PNO scan qcacld-2.0 to qcacld-3.0 propagation Host driver receives 11P channels as part of PNO scan because kernel enables 11P channels. This increases the scan time. Add changes to remove 11P channels from the received channel list in PNO scan Change-Id: Iede759dfabdc971309f3d1f68411d241f415b422 CRs-Fixed: 1017824 --- core/hdd/src/wlan_hdd_scan.c | 21 ++++++++++++--------- 1 file changed, 12 insertions(+), 9 deletions(-) diff --git a/core/hdd/src/wlan_hdd_scan.c b/core/hdd/src/wlan_hdd_scan.c index f5767944e6db..34cac57260e1 100644 --- a/core/hdd/src/wlan_hdd_scan.c +++ b/core/hdd/src/wlan_hdd_scan.c @@ -2136,13 +2136,16 @@ static int __wlan_hdd_cfg80211_sched_scan_start(struct wiphy *wiphy, num_ignore_dfs_ch++; break; } - - valid_ch[num_ch++] = - request->channels[i]->hw_value; - len += - snprintf(chList + len, 5, "%d ", - request->channels[i]-> - hw_value); + if (!cds_is_dsrc_channel( + cds_chan_to_freq( + request->channels[i]->hw_value))) { + valid_ch[num_ch++] = request-> + channels[i]->hw_value; + len += snprintf(chList + len, + 5, "%d ", + request->channels[i]-> + hw_value); + } break; } } @@ -2152,8 +2155,8 @@ static int __wlan_hdd_cfg80211_sched_scan_start(struct wiphy *wiphy, /* If all channels are DFS and dropped, * then ignore the PNO request */ - if (num_ignore_dfs_ch == request->n_channels) { - hdd_notice("All requested channels are DFS channels"); + if (!num_ch) { + hdd_notice("Channel list empty due to filtering of DSRC,DFS channels"); ret = -EINVAL; goto error; }
