/**
* @brief Get IP information for stations connected to the Wi-Fi AP interface
*
* @note If `CONFIG_LWIP_DHCPS` is disabled then `ip` address field will not be populated in sta list
* @note If `CONFIG_LWIP_DHCPS` is disabled then DHCP lookup is skipped; IPv4 may still be filled from the lwIP ARP cache when available.
* After DHCP (when enabled), any station still without an IP is resolved via ARP table on the same interface.
*
* @warning This API works only for the default Wi-Fi AP interface, i.e. esp-netif with key="WIFI_AP_DEF"
