[En-Nut-Discussion] Extra packet in ethernet packet

I found an issue in one of our products that is using Nut/OS 4.8.7 and AT91SAM7X256. If I send a packet with odd number of characters to my computer, an extra byte is padded at the end. Wireshark interprets it as "VSS-Monitoring Ethernet trailer". If the packet size is an even number, everything is fine. Most applications can handle this packet correctly. But some applications don't read the length in the header. They just process all characters in the packet and think this is a wrong message.
Did anyone see this problem before? How do you solve it?
Thank you very much.
