following :#include unit16_t htons (unit16_t host16bitvalue);unit32_t htons (unit32_t host32bitvalue);/* Returns the value of the network byte order */unit16_t Ntohs (unit16_t net16bitvalue);unit32_t Ntohs (unit32_t net32bitvalue); /* Returns the host byte order value */s should be treated as a 16-bit value (for example, TCP or Udpport). Consider L as a 32-bit value (e.g. IPV4 address);In addition to the byte order problem for each field in the proto
