Flavio Ceolin da49f2e440 coccicnelle: Ignore return of memset
The return of memset is never checked. This patch explicitly ignore
the return to avoid MISRA-C violations.

The only directory excluded directory was ext/* since it contains
only imported code.

Gil Pitney 71182cb294 driver: wifi: simplelink: Register socket offload operations.
If the SimpleLink WiFi driver is configured, and socket offload
enabled, this revectors the Zephyr BSD socket APIs to the SimpleLink
WiFi host driver BSD socket APIs, providing a
direct offload of the TCP/IP stack to the CC3220SF network
coprocessor.

Fixes #3706

Gil Pitney e189f59031 drivers: wifi: simplelink: enable Fast Connect policy
This enables the cc3220sf_launchxl to automatically
reconnect to the last good known access point (AP).

This method avoids the need to:
- perform a wifi scan for access points on bootup (saving power);
- include hard-coded SSID/passwords in the wifi application.
- include the wifi shell in the wifi application.
- rely on more complex provisioning methods;

Gil Pitney 42f51ef08d drivers: wifi: winc1500: Use offload_context instead of user_data.
The wifi_winc1500 driver's socket id is stored in
net_context->user_data, which may be overwritten later at
the socket layer, which also uses the net_context->user_data
field to store socket flags.

This patch introduces a dedicated offload_context field
for use by offload drivers, and updates the wifi_winc1500 offload
driver to use this field instead of user_data.

Fixes #8820

Gil Pitney c90170c5c5 drivers: wifi: simplelink: move files into a dedicated subdir
Place simplelink driver files into a subdirectory on par with
winc1500 subdirectory, to effect a better file organization.

No functional change in this patch.

Ulf Magnusson 21d4adef93 drivers: wifi: Kconfig: Remove redundant 'default n' properties
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.

This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

Gil Pitney 3bc77e88fb net: drivers: wifi: SimpleLink WiFi Offload Driver (wifi_mgmt only)
Initiate a SimpleLink WiFi Driver, implemented to the WiFi management
offload APIs for scan, connect, disconnect.

Also registers the DHCP-obtained IPv4 address upon connect.

This was validated on a cc3220sf_launchxl using the wifi
shell module from the Zephyr shell_module sample.

Tomasz Bursztyka ce947431e2 drivers/wifi: Move all winc1500 related code to its own directory
There will be other drivers, and mixing up all these files together will
create a mess so better having a dedicated place for winc1500, at least.

Exposing connect, disconnect and scan for now.

In case the iface is an instance of a WiFi offload device, the way it
manages scanning, connecting and disconnecting will be specific to that
device (not the mgmt interface obviously). In such case the device will
have to export relevantly a dedicated bunch of function to serve the
mgmt interface in a generic way.
