Re: [lwip-users] using etharp from ethernetif

[Leon Woestenberg]

Hello Sergio,

Some suggestions:

- make sure you have initialized "netif->hwaddr_len" to 6 in your netif
driver initialization.
- see if etharp.c sends ARP packets on the link.
- Generally, if you have DEBUGF output available, you might add more debug
statements
   to etharp.c to see whether your destination MAC addresses can be
resolved.
- Use ETHARP_DEBUGF to see if etharp.c builds an ARP table.

- disable ETHARP_QUEUEING (this is rather new code).

Regards,

Leon.

Normally, etharp_output()
