The AoE standard appears to have no CRC field. Is this in violation of the ethernet standard?

Question

I've been debugging AoE in one of my setups.

In it I noticed that the AoE packets do not seem to have checksum fields on the frames. I looked up the AoE specification and it doesn't seem to have CRC checksums on the ends of the packets defined.

Is the checksum field optional?

Answer 1

Found this AoE pdf with frame diagrams showing the crc.
It looks like originated from Coraid.
