[PATCH 0/6] wifi: rtw89: prepare packets offload to support newer firmware

[Ping-Ke Shih]

The packet offload is that driver prepare packets, such as QoS null or null
frames, and firmware uses these packets to tell AP about power state, for
example. The older firmware can prepare this itself, but further firmware
in the future will always need driver's help.

First three patches are to fix and adjust packet offload feature. The
latter three patches are to support new firmware type NORMAL_CE that
doesn't have LPS-PS mode but have P2P-PS and hardware scan.

[PATCH 1/6] wifi: rtw89: fix potential wrong mapping for pkt-offload

[Ping-Ke Shih]

From: Chin-Yen Lee <timlee@realtek.com>

When driver fails to send H2C to firmware for pkt-offload, we should not
update the pkt_list of driver, and need to release allocated pkt index to
avoid wrong mapping between driver and firmware.

[PATCH 2/6] wifi: rtw89: refine packet offload flow

[Ping-Ke Shih]

From: Chin-Yen Lee <timlee@realtek.com>

For upcoming firmware, driver needs to do packet offload to firmware to
ensure LPS protocol work properly, so we update current connection and
disconnect flow to maintain packet offload flow, and integrate with
current WoWLAN flow which also needs packet offload.

[PATCH 3/6] wifi: rtw89: add use of pkt_list offload to debug entry

[Ping-Ke Shih]

Driver can prepare pkt_list for firmware that only uses them to send out
the packets in specific situations. To understand the usage of current
status, and to check if there is leakage problem, dump bitmap and the
indices used by certain function.

An example looks like:

  map:
		...
        pkt_ofld:  3f 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ...
                [SCAN 0]: 3
                [SCAN 1]: 4

[PATCH 5/6] wifi: rtw89: 8852b: don't support LPS-PG mode after firmware 0.29.26.0

[Ping-Ke Shih]

Due to firmware size limit of 8852b, LPS-PG mode isn't supported after
0.29.26.0, and then we have more space to support other features, such as
P2P-PS, hardware scan and so on.

[PATCH 6/6] wifi: rtw89: 8852b: try to use NORMAL_CE type firmware first

[Ping-Ke Shih]

New firmware type NORMAL_CE is introduced to support P2P-PS and hardware
scan, but no LPS-PG mode. After this patch, old firmware with NORMAL type
can still work well.

The use of this new type is the same as before, so we add new type to
avoid taking wrong firmware. Then, driver log can also give clear
information about this change:

  rtw89_8852be 0000:03:00.0: Firmware version 0.29.26.0, cmd version 0, type 5
  rtw89_8852be 0000:03:00.0: Firmware version 0.29.26.0, cmd version 0, type 3
