Hi, Marek Thanks. Appreciate your comments. HWMP sequence number is 32bits or 4 octets. That's why it is defined as u32. Hi, Javier Thanks for your explanation and clarification. I will resubmit the patch for the changes. "In the section 11C.9.8.3 HWMP sequence numbering, Comparing HWMP sequence numbers is done using a circular modulo 232 comparison."
