====================
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
====================
