A few years back I had some data corruption issues for which I blamed
insufficient network equipment (Linksys SLM-2008 gigabit switches,
IIRC). Under high load, the switches would send garbage and then reboot.
Every client would get its own VLAN -- untagged on the client side,
tagged on the server side, so that clients didn't share a broadcast
domain. Since the switch had to recalculate Ethernet checksums after
tagging/untagging frames, checking the checksums would not even have
helped.
Replacing the switches seems to have helped, but protocol-wise, there is
no protection against switches munging packets. I think that adding a
checksum, at least for the payload would be an appropriate addition to
the AoE protocol.

I don't see how duplicate frames could become a problem as their content
is left intact.
