-Subject: [PATCH] brcmfmac: reduce timeout for action frame scan
-
-Finding a common channel to send an action frame out is required for
-some action types. 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.

-Subject: [PATCH] brcmfmac: fix full timeout waiting for action frame
- on-channel tx
-
-The driver sends an action frame down and waits for a completion signal
-triggered by the received BRCMF_E_ACTION_FRAME_OFF_CHAN_COMPLETE event
-to continue the process. 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.

-
-Along with F2 watermark (existing) configuration, F1 MesBusyCtrl
-should be enabled & sdio device RX FIFO watermark should be
-configured to avoid overflow errors.

-Subject: [PATCH] brcmfmac: Fix access point mode
-
-Since commit 1204aa17f3b4 ("brcmfmac: set WIPHY_FLAG_HAVE_AP_SME flag")
-the Raspberry Pi 3 A+ (BCM43455) isn't able to operate in AP mode with
-hostapd (device_ap_sme=1 use_monitor=0):
-
-brcmfmac: brcmf_cfg80211_stop_ap: setting AP mode failed -52
-
-So add the missing mgmt_stypes for AP mode to fix this.

- in HT mode
-
-Long/short preamble selection cannot be sampled separately, since it
-depends on the BSS state. Because of that, sampling attempts to
-currently not used preamble modes are not counted in the statistics,
-which leads to CCK rates being sampled too often.
-
-Fix statistics accounting for long/short preamble by increasing the
-index where necessary.
-Fix excessive CCK rate sampling by dropping unsupported sample attempts.
-
-This improves throughput on 2.4 GHz channels

-Subject: [PATCH] cfg80211: fix page refcount issue in A-MSDU decap
-
-The fragments attached to a skb can be part of a compound page. In that case,
-page_ref_inc will increment the refcount for the wrong page. Fix this by
-using get_page instead, which calls page_ref_inc on the compound head and
-also checks for overflow.
