Subject: [PATCH v10 0/2] wifi: mwifiex: add code to support host mlme

With host mlme:
Tested-by: <rafael.beims@...adex.com> #Verdin AM62 IW416 SD
Without host mlme:
Tested-by: Francesco Dolcini <francesco.dolcini@...adex.com> # 88W8997-SD

This series add host based MLME support to the mwifiex driver, this
enables WPA3 support in both client and AP mode.
To enable WPA3, a firmware with corresponding V2 Key API support is
required.
The feature is currently only enabled on NXP IW416 (SD8978), and it
was internally validated by NXP QA team. Other NXP Wi-Fi chips
supported in current mwifiex are not affected by this change.

v10:
   - Use eth_broadcast_addr() to set the broadcast address.
   - Add comment for constant used for the length of FW special 4 address
     management header.
   - Check host_mlme_enabled to decide if creating host_mlme_workqueue
     or not.
   - Use cpu_to_le16 instead of casting via (__force __le16).
   - Change the abbreviation "disasso" to "disassoc" of the printout message.

v9:
   - Remove redundent code.
   - Remove unnecessary goto target.  

v8:
   - Separate 6/12 from patch v7.
     As it's a bug fix not part of host MLME feature.
   - Rearrnage MLME feature into 2 patches:
     a. Add host based MLME support for STA mode.
     b. Add host based MLME support for AP mode.

v7:
   - Fix regression: Downlink throughput degraded by 70% in AP mode.
   - Fix issue: On STAUT, kernel Oops occurs when there is no association
     response from AP.
   - Fix issue: On STAUT, if AP leaves abruptly and deauth is missing,
     STA can't connect to AP anymore.
   - Fix regression: STA can't connect to AP when host_mlme is disabled
     (impact all chips).
   - Address reviewer comments.

v6:
   - Correct mailing sequence.

v5:
   - Add host base MLME support to enable WPA3 functionalities for both
     STA and AP mode.
   - This feature (WPA3) required a firmware with corresponding Key API V2
     support.
   - QA validation and regression have been covered for IW416.
   - This feature (WPA3) is currently enabled and verified only for IW416.
   - Changelogs since patch V4:
     a. Add WPA3 support for AP mode.
     b. Bug fix: In WPA3 STA mode, deice gets disconnected from AP
        when group rekey occurs.
     c. Bug fix: STAUT doesn't send WMM IE in association request when
        associate to a WMM-AP.

v4:
   - Refine code segment per review comment.
   - Add API to check firmware encryption key command version when
     host_mlme is enabled.

v3:
   - Cleanup commit message.

v2:
   - Fix checkpatch error (pwe[1] -> pwe[0]).
   - Move module parameter 'host_mlme' to mwifiex_sdio_device structure.
     Default only enable for IW416.
   - Disable advertising NL80211_FEATURE_SAE if host_mlme is not enabled.
