2023-03-07wifi: mac80211: introduce ieee80211_refresh_tx_agg_session_timer()Ryder Lee
This allows low level drivers to refresh the tx agg session timer, based on querying stats from the firmware usually. Especially for some mt76 devices support .net_fill_forward_path would bypass mac80211, which leads to tx BA session timeout clients that set a timeout in their AddBA response to our request, even if our request is without a timeout.

2023-03-07wifi: wireless: correct primary channel validation on 6 GHzMordechay Goodstein
The check that beacon primary channel is in the range of 80 MHz (abs < 80) is invalid for 320 MHz since duplicate beacon transmit means that the AP transmits it on all the 20 MHz sub-channels: 9.4.2.249 HE Operation element - ... AP transmits Beacon frames in non-HT duplicate PPDU with a TXVECTOR parameter CH_BANDWIDTH value that is up to the BSS bandwidth. So in case of 320 MHz the DUP beacon can be in upper 160 for primary channel in the lower 160 giving possibly an absolute range of over 80 MHz. Also this check is redundant alltogether, if AP has a wrong primary channel in the beacon it's a faulty AP, and we would fail in next steps to connect. While at it, fix the frequency comparison to no longer compare between KHz and MHz, which was introduced by commit 7f599aeccbd2 ("cfg80211: Use the HE operation IE to determine a 6GHz BSS channel").

2023-03-07wifi: wireless: return primary channel regardless of DUPMordechay Goodstein
Currently in case DUP bit is not set we don't return the primary channel for 6 GHz Band, but the spec says that the DUP bit has no effect on this field: 9.4.2.249 HE Operation element: The Duplicate Beacon subfield is set to 1 if the AP transmits Beacon frames in non-HT duplicate PPDU with a TXVECTOR parameter CH_BANDWIDTH value that is up to the BSS bandwidth and is set to 0 otherwise. So remove the condition for returning primary channel based on DUP. Since the caller code already marks the signal as invalid in case the indicated frequency is not the tuned frequency, there's no need to additionally handle this case here since that's already true for duplicated beacons on the non-primary channel(s).

2023-02-27wifi: brcmfmac: chip: Handle 1024-unit sizes for TCM blocksHector Martin
BCM4387 has trailing odd-sized blocks as part of TCM which have their size described as a multiple of 1024 instead of 8192. Handle this so we can compute the TCM size properly.

2023-02-27wifi: brcmfmac: chip: Only disable D11 cores; handle an arbitrary numberHector Martin
At least on BCM4387, the D11 cores are held in reset on cold startup and firmware expects to release reset itself. Just assert reset here and let firmware deassert it. Premature deassertion results in the firmware failing to initialize properly some of the time, with strange AXI bus errors. Also, BCM4387 has 3 cores, up from 2. The logic for handling that is in brcmf_chip_ai_resetcore(), but since we aren't using that any more, just handle it here.

2023-02-27wifi: brcmfmac: support CQM RSSI notification with older firmwareJohn Keeping
Using the BCM4339 firmware from linux-firmware (version "BCM4339/2 wl0: Sep 5 2019 11:05:52 version 6.37.39.113 (r722271 CY)" from cypress/cyfmac4339-sdio.bin) the RSSI respose is only 4 bytes, which results in an error being logged. It seems that older devices send only the RSSI field and neither SNR nor noise is included. Handle this by accepting a 4 byte message and reading only the RSSI from it.

2023-02-27wifi: brcmfmac: pcie: Provide a buffer of random bytes to the deviceHector Martin
Newer Apple firmwares on chipsets without a hardware RNG require the host to provide a buffer of 256 random bytes to the device on initialization. This buffer is present immediately before NVRAM, suffixed by a footer containing a magic number and the buffer length. This won't affect chips/firmwares that do not use this feature, so do it unconditionally for all Apple platforms (those with an Apple OTP).

2023-02-27wifi: brcmfmac: acpi: Add support for fetching Apple ACPI propertiesHector Martin
On DT platforms, the module-instance and antenna-sku-info properties are passed in the DT. On ACPI platforms, module-instance is passed via the analogous Apple device property mechanism, while the antenna SKU info is instead obtained via an ACPI method that grabs it from non-volatile storage. Add support for this, to allow proper firmware selection on Apple platforms.

2023-02-22wifi: rtw89: refine FW feature judgement on packet dropZong-Zhe Yang
The newer chips use the newer firmware branches, e.g. v027, v029. And, those firmware branches are supposed to support packet drop when they are just branched out. The initial firmware branch used by each chip is as below. * 8852A: v009 * 8852C: v027 * 8852B: v027 So, only 8852A may use firmware which doesn't support packet drop at runtime. To save trivial positive listing in firmware feature table, we change to reverse judgment. Besides, rtw89_mac_ptk_drop_by_band_and_wait() missed to check firmware feature before calling rtw89_fw_h2c_pkt_drop(). We also fix it.
