From Sake Blok :
Fix for Bug 1136 (TCP Checksum Validation)
TCP cksum 0xffff should not appear in TCP headers. RFC 1624 explains that it
can be generated by a (not-so-good) algorithm for incremental updates to the
tcp-checksum.
New behavior of wireshark when having cksum == 0xffff :
- use "Checksum: 0xffff [should be 0x0000 (See RFC 1624)]" in the
packet-detail pane
- set tcp.checksum_good to FALSE (just like checksum-offload packets)
- set tcp.checksum_bad to FALSE (just like checksum-offload packets)
- Generate an expert warning: "TCP Checksum 0xffff instead of 0x0000 (See RFC 1624)"
- add "[TCP CHECKSUM 0xFFFF]" instead of "[TCP CHECKSUM BAD]" to COL_INFO
