Hi, I have been looking deeper into my wireshark packet captures and found something that could be helpfull.
I can see that the Ethernet NIC at least does something. ARP BROADCAST traffic is seen. But i also found some packets...which have LG BITs set to 1 .. when i think 0 should be the correct value..something with Octets. *"the first 3 octets/first-half of a MAC-48/EUI-48 Address, correspond to the OUI (e.g.: MAC = 06:00:00:xx:xx:xx, OUI = 06:00:00), and the 2nd least significant bit of its first octet is used to differentiate "Universally" and "Locally" administered addresses). In other words, if we convert 06 (Hex) to 00000110 (Binary), we can see that the U/L bit is set to one, which means that it a locally administered address.* *Given this if we disable that bit, we get the matching "Universally Administered Address" 00000100 (Binary), 04 (Hex) -> "04:00:00", hence my question:"* This has something to do with the MAC adresses being locally administered .. and since whe can use Uboot and choose any Mac addr we want, this could make sense.. These types of Logs also apear in my Wireshark Capture files... ( these are not my org. logs) Ethernet II, Src: Microchi_8f:c6:a8 (d8:80:39:8f:c6:a8), Dst: Broadcast (ff:ff:ff:ff:ff:ff) Destination: Broadcast (ff:ff:ff:ff:ff:ff) Address: Broadcast (ff:ff:ff:ff:ff:ff) .... ..1. .... .... .... .... = LG bit: Locally administered address (this is NOT the factory default) .... ...1 .... .... .... .... = IG bit: Group address (multicast/broadcast) Source: Microchi_8f:c6:a8 (d8:80:39:8f:c6:a8) Address: Microchi_8f:c6:a8 (d8:80:39:8f:c6:a8) .... ..0. .... .... .... .... = LG bit: Globally unique address (factory default) .... ...0 .... .... .... .... = IG bit: Individual address (unicast) Type: IP (0x0800) Internet Protocol Version 4, Src: 0.0.0.0 (0.0.0.0), Dst: 255.255.255.255 (255.255.255.255) In the link below some similair Logs and problems regarding DHCP for example.
