Since a loop with several scan retry is used to find +the channel, a short wait time could be considered for each attempt. +This patch reduces the wait time from 1500 to 450 msec for each action +frame scan. + +This patch fixes the WFA p2p certification 5.1.20 failure caused by the +long action frame send time. + +Signed-off-by: Chung-Hsien Hsu <stanley.hsu@cypress.com> +Signed-off-by: Chi-Hsien Lin <chi-hsien.lin@cypress.com> +Signed-off-by: Kalle Valo <kvalo@codeaurora.org> +--- + drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.c | 9 ++++----- + 1 file changed, 4 insertions(+), 5 deletions(-) + +--- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.c ++++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.c +@@ -74,7 +74,7 @@ + #define P2P_AF_MAX_WAIT_TIME msecs_to_jiffies(2000) + #define P2P_INVALID_CHANNEL -1 + #define P2P_CHANNEL_SYNC_RETRY 5 +-#define P2P_AF_FRM_SCAN_MAX_WAIT msecs_to_jiffies(1500) ++#define P2P_AF_FRM_SCAN_MAX_WAIT msecs_to_jiffies(450) + #define P2P_DEFAULT_SLEEP_TIME_VSDB 200 + + /* WiFi P2P Public Action Frame OUI Subtypes */ +@@ -1141,7 +1141,6 @@ static s32 brcmf_p2p_af_searching_channe + { + struct afx_hdl *afx_hdl = &p2p->afx_hdl; + struct brcmf_cfg80211_vif *pri_vif; +- unsigned long duration; + s32 retry; + + brcmf_dbg(TRACE, "Enter\n"); +@@ -1157,7 +1156,6 @@ static s32 brcmf_p2p_af_searching_channe + * pending action frame tx is cancelled. + */ + retry = 0; +- duration = msecs_to_jiffies(P2P_AF_FRM_SCAN_MAX_WAIT); + while ((retry < P2P_CHANNEL_SYNC_RETRY) && + (afx_hdl->peer_chan == P2P_INVALID_CHANNEL)) { + afx_hdl->is_listen = false; +@@ -1165,7 +1163,8 @@ static s32 brcmf_p2p_af_searching_channe + retry); + /* search peer on peer's listen channel */ + schedule_work(&afx_hdl->afx_work); +- wait_for_completion_timeout(&afx_hdl->act_frm_scan, duration); ++ wait_for_completion_timeout(&afx_hdl->act_frm_scan, ++ P2P_AF_FRM_SCAN_MAX_WAIT); + if ((afx_hdl->peer_chan != P2P_INVALID_CHANNEL) || + (!test_bit(BRCMF_P2P_STATUS_FINDING_COMMON_CHANNEL, + &p2p->status))) +@@ -1178,7 +1177,7 @@ static s32 brcmf_p2p_af_searching_channe + afx_hdl->is_listen = true; + schedule_work(&afx_hdl->afx_work); + wait_for_completion_timeout(&afx_hdl->act_frm_scan, +- duration); ++ P2P_AF_FRM_SCAN_MAX_WAIT); + } + if ((afx_hdl->peer_chan != P2P_INVALID_CHANNEL) || + (!test_bit(BRCMF_P2P_STATUS_FINDING_COMMON_CHANNEL, |
