This series adds a new full-MAC Wi-Fi driver `nxpwifi` to support NXP IW61x
chip family. These chips are tri-radio single-chip solutions with Wi-Fi 6
(1x1, 2.4/5 GHz), Bluetooth 5.4, and IEEE 802.15.4. Communication with the
external host is via SDIO interface. The driver is tested on i.MX8M Mini
EVK in both STA and AP mode.

This driver is not based on mac80211. It derives from mwifiex, but due to
significant differences in firmware architecture, host command interface,
and supported features, it was not feasible to extend mwifiex without risk
of regressions. Thus, a new driver is introduced. Future NXP Wi-Fi chipsets
will also be supported under `nxpwifi`.

The driver passes checkpatch. WPA2/WPA3 personal/enterprise is currently
handled in host via wpa_supplicant/hostapd.

v4 adds support for TWT, monitor mode, WPA3 Enterprise Suite-B, and various
fixes and improvements. See below for full changelog.

Change history:

v5:
   - Fixed build errors introduced in v4.

v4:
   - Added support for TWT (STA mode)
   - Added support for Monitor mode
   - Added support for WPA3 Enterprise Suite-B
   - Bug fix: In BGN/AN HT40 mode, throughput was 50% lower than expected
   - Bug fix: In STA 2.4G HE40 mode, throughput was 80% lower than expected
   - Use wiphy work instead of general workqueue for cfg80211 ops
   - Introduced RCU protection for ba, rx_reorder, and sta_lists
   - Used per-TID spinlock for tx_ba / rx_reorder lists to improve
     concurrency
   - Replaced mutex_lock with wiphy_lock
   - Reverted "use tasklet for Rx" (back to workqueue)
   - Refactored HE capability handling for better clarity and
     maintainability
   - Used standard kernel helpers for MAC address handling
   - Replaced proprietary nxpwifi_ieee80211 with standard ieee80211_mgmt
     structure
   - Used u32_get_bits() for VHT capability field access
   - Replaced LOW_PRIO_TID with TC_PRIO_BESTEFFORT for skb priority
   - Removed static WPA/RSN OUI table; now derived from cipher suite ID
   - Removed redundant helper functions: has_vendor_hdr and has_ieee_hdr

v3:
   - Enable 802.11ax (Wi-Fi 6) for both AP and STA mode.
   - Extend driver verion string with hotfix number.
   - Remove Rx mlme work.
   - Remove all useless check of netif_carrier_ok().
   - Merge decl.h to cfg.h.
   - Remove unnecessary check for wiphy parameters setting.
   - Synchronize following commits from Mwifiex:
     wifi: mwifiex: replace open-coded module_sdio_driver()
     wifi: mwifiex: Fix interface type change
     wifi: mwifiex: Do not return unused priv in mwifiex_get_priv_by_id()
     wifi: mwifiex: increase max_num_akm_suites
     wifi: mwifiex: duplicate static structs used in driver instances
     wifi: mwifiex: keep mwifiex_cfg80211_ops constant
     wifi: mwifiex: Fix uninitialized variable in
                    mwifiex_cfg80211_authenticate()
     wifi: mwifiex: remove unnecessary checks for valid priv
     wifi: mwifiex: Fix memcpy() field-spanning write warning in
                    mwifiex_cmd_802_11_scan_ext()
     wifi: mwifiex: Use IRQF_NO_AUTOEN flag in request_irq()

v2:
   - Rename ioctl.h and sta_ioctl.c to cfg.h and sta_cfg.c.
   - Remove useless header file semaphore.h.
   - Use static variable for cookie.
   - Modify nxpwifi_register to use ERR_PTR, IS_ERR and PTR_ERR.
   - Use error number for error code.
   - Remove unnecessary private ie definitions.
   - Remove mutex async_mutex and related code.
   - Remove unnecessary work queue.
   - Add the support for PSK SHA256.
   - Use tasklet for Rx.
   - Remove unused functions.
   - Remove compile warning.

This seems to be working well for me, at least for Wifi. I'd like to get 
Bluetooth up as well. The bluetooth driver (btnxpuart) doesn't seem 
happy loading the bluetooh firmware:

[   35.930755] Bluetooth: hci0: Request Firmware: nxp/uartspi_n61x_v1.bin.se

[   41.358411] Bluetooth: hci0: command 0x1002 tx timeout

I think the "combo" firmware needs to be loaded by the WiFi driver 
right? I assume this isn't supported yet?

Hi Martyn,

Thanks for testing the nxpwifi driver. On our side, we haven’t seen issues
with Bluetooth on the NXP i.MX93 EVK platform, regardless of whether the nxpwifi
driver loads the Wi-Fi-only firmware or the combo firmware.

From your logs, it looks like you're loading the Wi-Fi-only firmware
(nxp/uartspi_n61x_v1.bin.se). If it were the combo firmware, the btnxpuart
driver would skip loading the BT firmware entirely, since it would already
be downloaded by the Wi-Fi driver.

To help us reproduce and investigate further, could you please share:
- Your test platform (SoC, board, etc.)
- Your test steps
- The exact firmware version you're using
Also, have you tried running Bluetooth in a BT-only scenario (without loading
the Wi-Fi driver)? Does that work correctly?

Thanks,  
Jeff

Yes, I'm currently using the wifi only firmware. If I'm not mistaken, 
that's the only firmware that the NXPWifi driver will currently use. It 
appears that it should be able to load `firmware_sdiouart`, but that 
doesn't appear to be set anywhere and thus it's not considered. I tried 
to rename the combo firmware to have the name used for the wifi only 
firmware, but that was failing for me (more about that in a moment).

Custom board based on Renesas RZ-G2L, using Ezurio Sona NX611 M.2 1216 
module.

Kernel is 6.17 with an added custom DT, a few patches for other hardware 
and the NXPWifi patch series.

Both btnxpuart and nxpwifi are built as modules.

The firmware itself is what Ezurio provide in their Yocto layer:

$ md5sum *
6a9307d27c3bdb3bde800265056ab217  sd_w61x_v1.bin.se
8a28ec7f1b77dbde0ac7568d0426c669  sduart_nw61x_v1.bin.se
d38935f03dbe6da7a9ac3daf58e640bf  uartspi_n61x_v1.bin.se


Looking a bit deeper, if I try and load the combined firmware, the 
bluetooth modules attempts to load before the WiFi driver has had a 
chance to complete loading the firmware which is resulting in the 
firmware failing.

If I blacklist the btnxpuart module (and rename the combo firmware),
it loads:

At the moment, booting and checking to see if the hardware has probed.
If it has, ensure I can connect to my wifi network and ensure that I can 
pass a little bit of traffic.

As above.

I hadn't. Just gave that a go and I seem to be getting the same failure 
(though :

Are there any BT patches that I'm missing?

Anyway the other reason I was commenting - when it's merged it should
just be a single patch, I think? So maybe provide a cover letter with a
commit message suitable for the entire driver and Signed-off-by? Not
sure how I should really handle this, tbh, but I guess that works.
