There are new pseudomodules for this driver:
- atwinc15x0_static_connect: Should behave as before, by trying to connect to an AP
by specified WIFI_SSIS and WIFI_PASS
- atwinc15x0_dynamic_connect: takes connection request via NETOPT_CONNECT
and provides the connection result via callback
- atwinc15x0_dynamic_scan: takes network scan requests via NETOPT_SCAN
and provides the scan result as a sorted list via callback
Currently when m2m_wifi_handle_events() fails, we end up in a busy
loop and the netdev thread becomes unusable.
Instead, reset (re-init) the WiFi module if this condition occurs.
While not ideal, it's certainly an improvement to the current situation.
I noticed the wifi module would not receive any router advertisements
while an esp8266 did just fine.
Turns out joining the multicast groups was not enabled.
With this it works as expected.
