Title:
  qemu/net/colo-compare.c:288: possible pointless code duplication ?

Status in QEMU:
  New

Bug description:
  qemu/net/colo-compare.c:288] -> [qemu/net/colo-compare.c:296]: (style)
  The if condition is the same as the previous if condition

  Source code is

      if (ppkt->tcp_seq == spkt->tcp_seq && ppkt->seq_end == spkt->seq_end) {
          if (colo_compare_packet_payload(ppkt, spkt,
                                          ppkt->header_size, spkt->header_size,
                                          ppkt->payload_size)) {
              *mark = COLO_COMPARE_FREE_SECONDARY | COLO_COMPARE_FREE_PRIMARY;
              return true;
          }
      }
      if (ppkt->tcp_seq == spkt->tcp_seq && ppkt->seq_end == spkt->seq_end) {
          if (colo_compare_packet_payload(ppkt, spkt,
                                          ppkt->header_size, spkt->header_size,
                                          ppkt->payload_size)) {
              *mark = COLO_COMPARE_FREE_SECONDARY | COLO_COMPARE_FREE_PRIMARY;
              return true;
          }
      }

  Maybe the second block was supposed to be different ?
