urtwn(4) / rtwn(4) drivers are merged - call for testing (Was: RTL8812AU / RTL8821AU driver)

[Andriy Voskoboinyk]

Hi everyone,

rtwn(4), urtwn(4) and urtwm (from previous emails) drivers were merged  
into a
single rtwn driver (plus rtwn_usb / rtwn_pci device glue); the code is
available on https://github.com/s3erios/rtwn repository. Among bugfixes /
code deduplication, there some new features too:

1) multi-vap support (one any wireless interface + one STA interface +
any number of monitor mode interfaces).
2) few new sysctls:
  * dev.rtwn.#.crypto - controls how to use hardware crypto acceleration
  * dev.rtwn.#.ratectl_selected
  * dev.rtwn.#.ratectl - selects current 'rate control' algorithm
(currently only 'none' and 'net80211' are supported; RTL8192CE needs  
testing
with the last).
3) (incomplete) power management support for RTL8188EU (requires firmware).
4) Short Guard Interval support.

It's known to work with RTL8188CUS, RTL8188EU and RTL8821AU; however,
it was never tested with RTL8192CE or RTL8812AU.

How-to-build:
1) download / checkout the repository.
2) apply 'patch-usbdevs.diff' against '/usr/src'
3) build and install rtwn module:
    cd $repository/sys/modules/rtwn && make && make install
4) build and install rtwn_usb/rtwn_pci:
    cd ../rtwn_usb && make && make install
    cd ../rtwn_pci && make && make install
5) unload previous && load current drivers:
    kldunload if_urtwn if_rtwn
    kldload /boot/modules/if_rtwn.ko /boot/modules/if_rtwn_usb.ko  
/boot/modules/if_rtwn_pci.ko
6) Use.
