Fixed, thanks for reporting.

From 30 seconds before a stable entry times out, a unicast requests are sent (only if the entry is still used for TX).
From 15 seconds before timeout, broadcasts are sent.

Not a real sophisticated algorithm, but it should do the trick, given that this is only a network bandwidth optimization.

I'm happy with that.  Do you have a patch that makes this change?

Currently all etharp_request() ARP requests are sent broadcast
I propose a feature which will cause the ARP requests to be first sent as unicast requests (to the cached hw address), and only after XXX (3?) failure attempts we will switch to broadcast requests.

This behavior is similar to how Linux ARP layer works.
