Add macros for R12A_RXDMA_PRO register (descriptions were seen in the
RTL8822B vendor driver) and merge 2 r21au_init_burstlen() copies.
No functional change intended.
This removes the direct WME info access in the ieee80211com struct and instead
provides a method of fetching the data. Right now it's a no-op but eventually
it'll turn into a per-VAP method for drivers that support it (eg iwn, iwm,
upcoming ath10k work) as things like p2p support require this kind of behaviour.
Tested:
* ath(4), STA and AP mode
TODO:
* yes, this is slightly stack size-y, but it is an important first step
to get drivers migrated over to a sensible WME API. A lot of per-phy things
need to be converted to per-VAP before P2P, 11ac firmware, etc stuff shows up.
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).
Since device can pass multiple frames in a single payload temporary
Rx buffer was big enough to hold all of them; now the driver can
concatenate a single frame from multiple payloads.
The Rx buffer size may be configured via tunable (dev.rtwn.%d.rx_buf_size).
Tested with:
- rtl8188cus, rtl8188eu and rtl8821au (STA mode).
- (by kevlo) rtl8192cu and rtl8188eu.

Remove any chipset specific usage of Rx descriptor structure / bits
from common code to prevent misuse of fields that may differ
between various chipsets.
Checked with: RTL8821AU in STA mode.

- 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
sc_set_media_status() callback may involve some generic code in addition to
firmware-specific part (e.g., link status register setup for RTL8188E);
so, remove 'RTWN_WITHOUT_UCODE' ifdefs around it.
Tested with RTL8188CUS, RTL8188EU and RTL8821AU, STA mode.
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.

- Use ni_txparms directly instead of calculating them manually every time
- Move M_EAPOL flag check upper; otherwise it may be skipped due to
'ucastrate' / 'mcastrate' check
- Use 'mgtrate' for control frames too (see ifconfig(8), mgtrate parameter)
- Add few more M_EAPOL checks where it was missing (zyd(4), ural(4),
urtw(4))
- Few unrelated cleanups
Tested with:
- Intel 6205 (iwn(4)), STA mode;
- WUSB54GC (rum(4)), HOSTAP mode + RTL8188EU (rtwn(4)), STA mode.

Use device-specific Rx buffer size to ensure that data will not be
truncated + add a warning if truncation was detected (the driver
cannot handle this case correctly yet).
Tested with:
- RTL8188CUS, RTL8188EU and RTL8821AU, STA / AP modes.
(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)

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

- Provide an additional defragmentation routine for frames larger
than MCLBYTES; that is required by A-MSDU / Atheros Fast-Frames
