Subject: [PATCH v11 1/2] wifi: mwifiex: add host mlme for client mode
Add host based MLME to enable WPA3 functionalities in client mode.
This feature required a firmware with the corresponding V2 Key API
support. The feature (WPA3) is currently enabled and verified only
on IW416. Also, verified no regression with change when host MLME
is disabled.

v11:
- add proper and useful comment for mwifiex_cfg80211_probe_client().
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.
v8:
- first full and complete patch to support host based MLME for client
mode.
