This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 supports 8822BE and 8822CE chips, and will be able to support
multi-vif combinations in run-time.

For now, only PCI bus is supported, but rtw88 was originally designed
to optionally support three buses includes USB & SDIO. USB & SDIO modules
will soon be supported by rtw88, with configurable core module to fit
with different bus modules in the same time.

For example, if we choose 8822BE and 8822CU, only PCI & USB modules will
be selected, built, loaded into kernel. This is one of the major
difference from rtlwifi, which can only support specific combinations.

Another difference from rtlwifi is that rtw88 is designed to support
the latest Realtek 802.11ac wireless network chips like 8822B and
8822C series. Compared to the earlier chips supported by rtlwifi like
the 802.11n 8192EE chipset or 802.11ac 8821AE/8812AE chips, newer ICs
have different MAC & PHY settings, such as new multi-port feature for the
MAC layer design and Jaguar2/Jaguar3 PHY layer IPs.

Multi-Port feature is also supported under rtw88's software architecture.
rtlwifi can only support one vif in the same time, most because of the
hardware limitations for early chips, hence the original design of it
also restricts the usage of multi-vif support, so latest chipset seems not
take advantages from its new MAC engine.

However, rtw88 can run multiple vifs concurrently by holding them on
hardware ports provided by MAC engine, hence can easily start different
roles on a single device.

Based on the reasons mentioned before, we implemented rtw88. It had many
authors, they are listed here alphabetically:

v2

 - add comment for watch dog


v3

 - change tree location to wireless-next


v4

 - remove useless "T:" and "W:" lines in MAINTAINERS file, as we don't have
   our own tree and wiki page now
 - rename patch 13 to "add MAINTAINERS entry"
 - use skb_pull to remove tx descriptors before reporting tx status to
   mac80211 stack, otherwise mac80211 tx status will always fail to match
   addr1/addr2 and will finally trigger to disconnect
 - return back to operating channel when we leave IDLE state, as mac80211
   stack expected. If we don't, mac80211 will assume we are already at
   channel 1 and start to scan. And we will never be able to connect to
   APs that are in channel 1. (which is most AP's default channel)
 - wait for async firmware load successfully, otherwise some slower platform
   might start to download firmware before loaded. And system crashes with a
   null pointer accessed.
 - fix typo for mac.h __RTW_MAc_H__ -> __RTW_MAC_H__
