29ed2a79de mt76: mt7615: fix survey channel busy time
Like on mt7603, MIB status register 16 tracks CCA time, but does not
include tx time. Switch to status register 9 to includ NAV and tx
time as well.

Kalle Valo says:

====================
wireless-drivers-next patches for 5.5

First set of patches for 5.5. The most active driver here clearly is
rtw88, lots of patches for it. More quiet on other drivers, smaller
fixes and cleanups all over.

This pull request also has a trivial conflict, the report and example
resolution here:

https://lkml.kernel.org/r/20191031111242.50ab1eca@canb.auug.org.au

Major changes:

rtw88

* add deep power save support

* add mac80211 software tx queue (wake_tx_queue) support

* enable hardware rate control

* add TX-AMSDU support

* add NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 support

* add power tracking support

* add 802.11ac beamformee support

* add set_bitrate_mask support

* add phy_info debugfs to show Tx/Rx physical status

* add RFE type 3 support for 8822b

ath10k

* add support for hardware rfkill on devices where firmware supports it

rtl8xxxu

* add bluetooth co-existence support for single antenna

iwlwifi

* Revamp the debugging infrastructure

7bd0650be6 mt76: dma: fix buffer unmap with non-linear skbs
mt76 dma layer is supposed to unmap skb data buffers while keep txwi
mapped on hw dma ring. At the moment mt76 wrongly unmap txwi or does
not unmap data fragments in even positions for non-linear skbs. This
issue may result in hw hangs with A-MSDU if the system relies on IOMMU
or SWIOTLB. Fix this behaviour properly unmapping data fragments on
non-linear skbs.

2ce113de31 mac80211: simplify TX aggregation start
There really is no need to make drivers call the
ieee80211_start_tx_ba_cb_irqsafe() function and then
schedule the worker if all we want is to set a bit.

Add a new return value (that was previously considered
invalid) to indicate that the driver is immediately
ready for the session, and make drivers use it. The
only drivers that remain different are the Intel ones
as they need to negotiate more with the firmware.
