Hello,
I have disabled ARP_QUEUEING to be sure if a packet was sent on the
wire. If link is up but on a ARP request is not response, the lwip
just printf LWIP_DEBUGF(ETHARP_DEBUG | LWIP_DBG_TRACE, ("etharp_query:
Ethernet destination address unknown, queueing disabled, packet %p
dropped\n", (void *)q));.
The return value is based on etharp_request(netif, ipaddr). The ARP
request is always sent so ERR_OK is returned to netconn_sendto.
Is there a possibility to find out if packet was really sent with
disabled ARP_QUEUEING?
Regards,
Martin
