This 64 bytes includes Ethernet header, NC-SI header and payload, pldm
header and payload.
                   Some pldm commands payload is less than 26.  So we added
remaining bytes to match with 64 and which is 4 bytes aligned.

Also you can write this on one line:

    Kumar : Ack. Will update in the next patch set.
