Guess that ARP_MAXAGE which is set to 20 minutes explains the first part of
my question.
And scrolling thru the code I guess that there is a way to configure lwip in
such a way that the IPs are not removed from the cache?
And, after removing the IP from the cache the update of the cache (and
sending the reply), can this behavior controlled or configured?
See the trace below.
If I am right, the first attempt to update the cache of lwip is found in 36,
5 seconds later?
And the ping reply to 28 is found at 50, 320 seconds delayed?
Why?
