The test tries all combination of len1, > len2, and len3. To minimize the running time, bytes per checksum is set to be > 4 bytes, each packet size is set to be bytes per checksum, and each block > contains 2 packets. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
