* wifi: ARP gratuitous API for wifi station mode * fix with lwip1 * update comment * update API to allow changing interval on the fly * update API * remove debug lines * mock lwIP's etharp_request() * unsigned interval * use scheduled ticker * ticker: +attach_ms_scheduled_accurate ticker: +comment gratuitous: use attach_ms_scheduled_accurate * move to experimental namespace * fix for lwIP-v1.4 * attempt to make pio happy * use directly ETSTimer instead of Ticker
