This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtwlan 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 rtwlan was originally designed
to optionally support three buses includes USB & SDIO. USB & SDIO modules
will soon be supported by rtwlan, 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 rtwlan 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 rtwlan'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, rtwlan 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 rtwlan. It had many
authors, they are listed here alphabetically:

v3

 - missing rcu list traverse for vif_list

v2

 - rename from rtwlan to rtw88
 - remove lots of magic numbers
 - add pci null entry for auto load on boot
 - add rtwdev->mutex to protect against mac80211 callbacks
 - add rcu lock protection for vif_list and sta_list
 - refine bits & endian macros to use helper functions provided by kernel
   instead of create new ones
 - ieee80211_free_txskb for tx path dropped packets
 - not register iface_combination since now only one vif is allowed
 - some fixes suggested by Stanislaw
