This driver allow to use Zephyr native IP stack or the IP stack provided
by HAL / WiseConnect.
The WiseConnect implementation may take advantage of the specific
features provided by the 917 (power consumption, speed,
validation...).
Some notable features are not available with this interface:
- It seems Zephyr does not provide API to offload multicast membership
management. User should be to directly call WiseConnect APIs
- Support for ICMP frames is difficult. Note that WiseConnect
automatically answer to ping request. It is just not possible to
send ping requests and receive ping responses.
- Zephyr and WiseConnect both support TLS offloading. However this
patch does not implement it.
- Reentrancy in the WiseConnect side is uncertain.
This implementation has been tested with samples/net/wifi/ (which relies
on subsys/net/lib/shell).
