Introducing config option `CONFIG_ESP_NETIF_SET_DNS_PER_DEFAULT_NETIF` to overcome LWIP limitation of using global DNS server info. This config option enables LWIP callbacks to collect per netif DNS server info and then restores global DNS servers of whichever network interface is selected as default. LWIP submodule update v5.2: git log --oneline f1746813..3a3d1fb3 - dns: Allow storing dnsserver per netif (espressif/esp-lwip@3a3d1fb3) - api_msg: Fix unused local variable if LWIP_NETCONN_SEM_PER_THREAD=1 (espressif/esp-lwip@aa4f6e78) - lwip: fix gcc -fanalyzer warnings (espressif/esp-lwip@4297782b)

The value of 0 indicates the IP lost timer is disabled, otherwise the timer is enabled.
|
|
|
|
The IP address may be lost because of some reasons, e.g. when the station disconnects
|
|
from soft-AP, or when DHCP IP renew fails etc. If the IP lost timer is enabled, it will
|
|
be started everytime the IP is lost. Event SYSTEM_EVENT_STA_LOST_IP will be raised if
|
|
the timer expires. The IP lost timer is stopped if the station get the IP again before
|
|
the timer expires.

Enable if esp_netif_receive() should return error code. This is useful to inform upper layers
|
|
that packet input to TCP/IP stack failed, so the upper layers could implement flow control.

This option is disabled by default due to backward compatibility and will be enabled in v6.0 (IDF-7194)
