5f792f7478 rtwn(4): de-hardcode ('h/w rate index' - 'corresponding MCS index') constant 2018-03-16 01:03:10 +00:00

8f1ef22fca rtwn(4): reset Tx power values before calling get_txpower()
for RTL8192C / RTL8188E (like it is done for other chipsets).

0cc18edf18 rtwn(4): some initial preparations for (basic) VHT support.
Rename RTWN_RIDX_MCS to RTWN_RIDX_HT_MCS before adding 802.11ac
MCS rate indexes (they have different offset).

No functional change intended.

5c7083ce99 rtwn(4): change type for Tx power values (RTL8192C / RTL8188EU).
Tx power values can easily fit into uint8_t + only 8 bits are written
to registers; values may overflow only in case if ROM contains
malformed data (but limit is checked anyway).

Tested with RTL8188CUS, dev.rtwn.1.debug=0x2000 (no changes).

2cd325579c - Fix incorrect values in the computation of CCK and OFDM transmit power
for the rtl8188eu chipset
- Rename struct r92c_rom member names: s/channel_plan/reserved5/,
  s/xtal_calib/channel_plan to be compliant with definitions of the efuse
  in vendor hal_pg.h

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;

 - 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)

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.

a14f9888d9 rtwn: enable 11n support for RTL8188CE.
- Increase Rx buffer size from MCLBYTES to MJUMPAGESIZE.
- Provide an additional defragmentation routine for frames larger
than MCLBYTES; that is required by A-MSDU / Atheros Fast-Frames
support to work with current Tx path implementation.

Enabled features list for RTL8188CE:
- Atheros Fast-Frames;
- A-MPDU (Tx / Rx);
- A-MSDU (Tx / Rx; 4k only);
- Short Guard Interval.

Tested with:
- RTL8188CE (STA+AP) + RTL8821AU (STA).
- RTL8188CE (STA) + RTL8188CUS (AP).

NOTE: some multi-vap configurations (e.g., STA+IBSS) are not stable;
that will be fixed later.

Tested with:
 - RTL8188CE, STA + AP mode;

 - RTL8188CUS, IBSS 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.
