rtwn: announce VHT support for RTL8812AU/RTL8821AU.

2025-01-09T00:52:12+00:00

Although the transmit path doesn't yet support VHT rates (because
the rate control and rate representation in net80211 doesn't yet
know about VHT rates) the NIC will receive VHT frames but only
transmit HT frames.

Locally tested:

* RTL8812AU, STA mode

rtwn: set the maximum A-MPDU size correctly for RTL8812AU/RTL8821AU

2025-01-08T02:32:56+00:00

The vendor driver sets it to 64k or 128k depending upon chipset,
along with bit 31 being set in hal/rtl8812a_hal_init.c:SetHwReg8812A().

rtwn: create a new HAL routine for enabling STA mode beacon processing

2024-12-20T20:40:19+00:00

For some NICs (notably the rtl8192cu that I'm working on) the
firmware rate adaptation requires beacon processing to be enabled.

Instead of making assumptions in the if_rtwn beacon routines (and
honestly all of that should be in the HAL too), create a HAL method
for enabling/disabling beacon processing specifically in STA mode.

Since this isn't necessarily required for all NICs (notably the RTL8188E
NICs, where some will do firmware rate control and some will require
driver rate control), only enable it for the RTL8192CU and RT8192EU.

The RTL8188E and RTL8812/RTL8821 just have no-op routines for now.

Locally tested:

* RTL8192CU, STA mode

rtwn: add APIs for setting transmit power

2024-12-18T23:45:24+00:00

The RTL8188/RTL8192/RTL8821/RTL8812 NICs all seem happy to have
their transmit power changed at runtime - and it does seem to do
what's expected - the transmit power level does change.

So, add the API call here, even though it's all currently no-ops.
A follow-up commit will land changes for the chipsets to both
limit transmit power to the configured / regulatory limit AND
allow reconfiguration at runtime.

rtwn: add placeholder for the per-MACID rate report

2024-12-07T00:22:47+00:00

Some chipsets (such as the RTL8188E) have firmware which supports
a second kind of TX report - instead of a per-packet TX report,
it can generate a per-MACID summary of packet success/failure counters.

This would be helpful for those chips to cut back on the USB traffic
to get rate control feedback for the driver based rate control we're
currently using.

This is a no-op; it just gets the pieces in place for future work.

rtwn: enable HT40 for RTL8821/RTL8812 series NICs

2024-12-07T00:22:39+00:00

HT40 works fine in 2GHz and 5GHz modes in both 1 and 2 stream
scenarios, so just enable it here.

rtwn(4): decode some bit fields + merge duplicate code.

2018-06-19T00:38:28+00:00

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.
