7f74097165 rtwn_usb(4): fix Tx instability with RTL8192CU chipsets
- Fix data frames transmission via POWER_STATUS register setup -
it seems to be set by MACID_CONFIG firmware command, which was broken*
in r290439 and later disabled in r307529.

We can re-enable it later if / when firmware rate adaptation will be
ready; however, this step will be required anyway - for firmware-less
builds.

- Force RTS / CTS protection frame rate to CCK1 (this rate works fine
without any additional setup; no better workaround is known yet).

The problem was not observed on the channel 1 or with CCK1 rate enforced
('ifconfig wlan0 ucastrate 1' for 11 b/g; not possible for 11n networks
due to ifconfig(8) bug).

* I'm not sure if it works before r290439 because - AFAIR - I never seen
firmware rate adaptation working for 10-STABLE urtwn(4)
(It needs EN_BCN bit set and RSSI updates at least).

Tested with RTL8188CUS in STA mode
(in regular mode and with disabled MRR - DARFRC*8 is set to 0)

fdc9504f51 rtwn_usb(4): add IQ calibration support for RTL8192CU
The code is similar to the one for RTL8188E* and probably
should be shared with RTL8188CE (needs to be tested).

Checked with RTL8188CUS, 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)

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

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.
