[PATCH 0/7] rtw88: regular update and fixes

[yhchuang]

From: Yan-Hsuan Chuang <yhchuang@realtek.com>

This patchset adds some regular updates and fixes for the driver.

For the RA info and SGI fix, we found a little throughput
degradation under some situations. Fix it.

For the TX descriptor update, the driver asks the hardware to
update the sequence for some of the frames, such as management
frames, or the frames that are downloaded to the hardware.

The coex and the beacon enable/disable update are most for the
AP mode, the coex update can prevent sometimes the AP is not
able to transmit frames. The other can let the AP to disable
or enable the beacon.

[PATCH 1/7] rtw88: fix LDPC field for RA info

[yhchuang]

From: Tsang-Shian Lin <thlin@realtek.com>

Convert the type of LDPC field to boolen because
LDPC field of RA info H2C command to firmware
is only one bit.

[PATCH 2/7] rtw88: fix short GI capability based on current bandwidth

[yhchuang]

From: Tsang-Shian Lin <thlin@realtek.com>

Fix the transmission is not sent with short GI under
some conditions even if the receiver supports short GI.
If VHT capability IE exists in the beacon, the original
code uses the short GI for 80M field as driver's short GI
setting for transmission, even the current bandwidth is
not 80MHz.

Short GI supported fields for 20M/40M are informed in HT
capability information element, and short GI supported
field for 80M is informed in VHT capability information
element.

These three fields may be set to different values.
Driver needs to record each short GI support field for
each bandwidth, and send correct info depends on current
bandwidth to the WiFi firmware.

[PATCH 3/7] rtw88: update tx descriptor of mgmt and reserved page packets

[yhchuang]

From: Tzu-En Huang <tehuang@realtek.com>

Previous settings for TX descriptors of and reserved page packets
are insufficient.

For the sequence number of packets downloaded to reserved page, it
should be filled by hardware.
And for ps-poll packets in reserved page, to prevent AID being
changed by hardware, NAVUSEHDR should be set.
Additionally, the rate should be adjusted based on the current band
for mgmt and reserved page packets.

[PATCH 4/7] rtw88: coex: only skip coex triggered by BT info

[yhchuang]

From: Yan-Hsuan Chuang <yhchuang@realtek.com>

The coex mechanism used to skip upon the freeze flag is raised.
That will cause the coex mechanism being skipped unexpectedly.
Coex only wanted to keep the TDMA table from being changed by
BT side.

So, check the freeze and reason, if the coex reason is coming
from BT info, skip it, to make sure the coex triggered by Wifi
itself can work.

This is required for the AP mode, while the control flow is
different with STA mode. When starting an AP mode, the AP mode
needs to start working immedaitely after leaving IPS, and the
freeze flag could be raised. If the coex info is skipped, then
the AP mode will not set the antenna owner, leads to TX stuck.

[PATCH 5/7] rtw88: add ieee80211_ops::change_interface

[yhchuang]

From: Yan-Hsuan Chuang <yhchuang@realtek.com>

Sometimes mac80211 will just ask driver to change the interface
instead of to remove and then add a new one. And for driver, to
change the interface is just simply to remove and add a new one
but change the type of it.

[PATCH 7/7] rtw88: add h2c command in debugfs

[yhchuang]

From: Tzu-En Huang <tehuang@realtek.com>

It's very useful to send H2C command for debug usage. Add an entry
for sending H2C command to firmware.

usage example:
echo 42,00,00,43,02,00,00,00 > /sys/kernel/debug/ieee80211/phyX/rtw88
