5acae76adf rtwn: drop obsolete (since r319460) code. 
Tested with RTL8188EU, STA mode.

6b322760df rtwn: remove out-of-bounds access + fix debug output. 
Omit unused rates while initializing / dumping Tx power values.

They were not accessed anywhere (except for debugging), so this is
(mostly) no-op.

Tested with
 * RTL8188EU, STA mode.
 * RTL8812AU, STA mode.

09606165a0 rtwn: export more stats to net80211 
Setup more ieee80211_rx_stats fields for received frames:
 - pktflags:
  * IEEE80211_RX_F_FAIL_FCSCRC;
  * IEEE80211_RX_F_AMPDU;
  * IEEE80211_RX_F_AMPDU_MORE;
  * IEEE80211_RX_F_SHORTGI;
 - rate flags (CCK, OFDM, HT);
 - width;
 - phytype;
 - rate;
 - rx_tsf;
 - rssi;
 - nf;
 - ieee, freq (RTL8188EU only, when ht40 support is disabled).

Tested with:
 - RTL8188CE, RTL8188EU, RTL8821AU (STA / AP modes, i386)
 - (by kevlo) RTL8188EU and RTL8812AU (amd64)

b8ad00b0ed rtwn: add (untested) radar detection support for RTL8821AU 
(disabled by default).

To enable it, dev.rtwn.%d.radar_detection tunable need to be set
to a nonzero value.

Tested with RTL8821AU, AP mode (no radar events were seen - so,
I have no idea if it is really correct / working)

12bc234158 Merge r92c_init_rf_common() into r92c_init_rf(). In r88eu_attach.c, we could 
use r92c_init_rf() rather than r92c_init_rf_common() when sc_init_rf()
callback is invoked.

While here, constantly use RF chain instead of RF path in comment.

800762ee73 rtwn: drop excessive includes. 
Since rom_defs.h is included in rxxx_var.h there is no need to
include both of them.

c15d869233 rtwn: fix Rx filter setup for some multi-vap configuratons. 
- Correctly refresh Rx filter when AP (IBSS) vap is created after STA vap.
- Block any RCR updates during TSF correction (IBSS mode).
- Set CBSSID* bits during vap creation, not when it was started / stopped.
- Cache current state to prevent unnecessary register reads.

Tested with RTL8188CE, STA + AP mode.

7453645f2a rtwn(4), urtwn(4): merge common code, add support for 11ac devices. 
All devices:
- add support for rate adaptation via ieee80211_amrr(9);
- use short preamble for transmitted frames when needed;
- multi-bss support:
 * for RTL8821AU: 2 VAPs at the same time;
 * other: 1 any VAP + 1 sta VAP.
RTL8188CE:
- fix IQ calibration bug (reason of significant speed degradation);
- add h/w crypto acceleration support.
USB:
- A-MPDU Tx support;
- short GI support;
Other:
- add support for RTL8812AU / RTL8821AU chipsets
(a/b/g/n only; no ac yet);
- split merged code into subparts:
 * bus glue (usb/*, pci/*, rtl*/usb/*, rtl*/pci/*)
 * common (if_rtwn*)
 * chip-specific (rtl*/*)
- various other bugfixes.

Due to code reorganization, module names / requirements were changed too:
urtwn urtwnfw -> rtwn rtwn_usb rtwnfw
rtwn  rtwnfw  -> rtwn rtwn_pci rtwnfw

Tested with RTL8188CE, RTL8188CUS, RTL8188EU and RTL8821AU.
