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

Hi Dusan,

Ethernut is blah.205 and blah.1 is your management console,
right? I'm now aware, that due to the nature of SNMP, the
start of a management console indeed causes an ARP shower.

To our problem: I assume that both traps are created by
two different Nut/OS threads. Is this correct?
