I'm surprised that the protocol packets don't include an end-to-end

On the other hand, if this is a significant problem then NFS/iscsi IP
checksumming may not save your data either, since the IP checksum is
so weak. For large volumes of data you care about the integrity of,
you probably really want an end-to-end CRC.
Oops. The Ethernet CRC is end-to-end on a LAN, even if it's switched.
