However, the action frame could be transmitted +either on the current channel or on an off channel. For the on-channel +case, only BRCMF_E_ACTION_FRAME_COMPLETE event will be received when +the frame is transmitted, which make the driver always wait a full +timeout duration. This patch has the completion signal be triggered by +receiving the BRCMF_E_ACTION_FRAME_COMPLETE event for the on-channel +case. + +This change fixes WFA p2p certification 5.1.19 failure. + +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 | 17 +++++++++++++++-- + drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.h | 2 ++ + 2 files changed, 17 insertions(+), 2 deletions(-) + +--- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.c ++++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.c +@@ -1464,10 +1464,12 @@ int brcmf_p2p_notify_action_tx_complete( + return 0; + + if (e->event_code == BRCMF_E_ACTION_FRAME_COMPLETE) { +- if (e->status == BRCMF_E_STATUS_SUCCESS) ++ if (e->status == BRCMF_E_STATUS_SUCCESS) { + set_bit(BRCMF_P2P_STATUS_ACTION_TX_COMPLETED, + &p2p->status); +- else { ++ if (!p2p->wait_for_offchan_complete) ++ complete(&p2p->send_af_done); ++ } else { + set_bit(BRCMF_P2P_STATUS_ACTION_TX_NOACK, &p2p->status); + /* If there is no ack, we don't need to wait for + * WLC_E_ACTION_FRAME_OFFCHAN_COMPLETE event +@@ -1518,6 +1520,17 @@ static s32 brcmf_p2p_tx_action_frame(str + p2p->af_sent_channel = le32_to_cpu(af_params->channel); + p2p->af_tx_sent_jiffies = jiffies; + ++ if (test_bit(BRCMF_P2P_STATUS_DISCOVER_LISTEN, &p2p->status) && ++ p2p->af_sent_channel == ++ ieee80211_frequency_to_channel(p2p->remain_on_channel.center_freq)) ++ p2p->wait_for_offchan_complete = false; ++ else ++ p2p->wait_for_offchan_complete = true; ++ ++ brcmf_dbg(TRACE, "Waiting for %s tx completion event\n", ++ (p2p->wait_for_offchan_complete) ? ++ "off-channel" : "on-channel"); ++ + timeout = wait_for_completion_timeout(&p2p->send_af_done, + P2P_AF_MAX_WAIT_TIME); + +--- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.h ++++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.h +@@ -124,6 +124,7 @@ struct afx_hdl { + * @gon_req_action: about to send go negotiation requets frame. + * @block_gon_req_tx: drop tx go negotiation requets frame. + * @p2pdev_dynamically: is p2p device if created by module param or supplicant. ++ * @wait_for_offchan_complete: wait for off-channel tx completion event. + */ + struct brcmf_p2p_info { + struct brcmf_cfg80211_info *cfg; +@@ -144,6 +145,7 @@ struct brcmf_p2p_info { + bool gon_req_action; + bool block_gon_req_tx; + bool p2pdev_dynamically; ++ bool wait_for_offchan_complete; + }; + + s32 brcmf_p2p_attach(struct brcmf_cfg80211_info *cfg, bool p2pdev_forced); |
