That's consistent with a hardware checksum offload mechanism or similar
data-garbling scheme.

Check "netstat -ni" and "netstat -s" output to see if there are any
counters bouncing upwards.  (Depending on OS version, there's also
"dladm show-link -s" or "dlstat show -h".)  Also, depending on the
driver, "kstat" may be helpful in getting really low-level diagnostic
information.
