[En-Nut-Discussion] Re: En-Nut-Discussion] Duplicate ARPs (was: Time needed to get packet from RTL on ATmega128)

[Dusan Ferbas]

Hi Harald,

with Ethereal I can measure only time at RTL ethernet side. You can find 
attached a piece of traffic capture. I do not know if this conference can 
handle attachments, so I am sending a copy directly to you.

Initially every 30ms (but sometimes they are sending at 50us) there is an 
ARP request.

Then Nut/OS requests with ARP, response in 0,2 ms. After 1 ms another ARP 
request, response after 0,1 ms. SNMP trap after 0,23 ms, another one after 
2,3 ms. Why 2nd ARP request after 1 ms ?
