I will maybe need to implement the autonegotiation anyway because it shows that
some switches are non compliant to the ieee 802.3 but work with compliant
devices. But Ronja is noncompliant too because it starts sending the packets
immediately and doesn't wait for 3 link integrity pulses before starting to
transmit. So the improperly implemented device doesn't count any link integrity
pulses (it should also count the packets) and doesn't come up.

It happens only if Ronja is under constant broadcast as we had in our RTP
test. Someone has to put a hand in from of the RX for a while or disconnect
the RX for a moment to bring the link up.

This of course doesn't need autonegotiation, just counting the link integrity
pulses, but if I should already have the mechanism to identify the pulses, it
shouldn't probably be a big issue to add a CPU to send replies. At least it
would probably remove the complicated link integrity generating logic which
contains two counters, two large gates etc.
