lwip assertion: esp_add_netif: Double add #306
Description
I've been running my cbu-based devboard for a few days continuously and logging via serial. Log configuration:
bk72xx:
board: cb2s
framework:
sdk_silent: "none"
loglevel: VERBOSE
options:

During this time I rebooted my router twice and after each time I observed the following assertion, followed by a WDT reset:

The log is scrambled a bit, but it seems that mdns_netif_ext_status_callback() incorrectly handles some combinations of "reason" parameters which eventually causes calling mdns_resp_add_netif (lwip function) twice for the same netif, which triggers an assertion. Possible that it was broken by #263
