Comment # 6 on bug 11418 from 
The checksum behaviour is correct. The packet checksum is indeed correct. RFC
2460 is clear that the payload length used in the pseudo-header is the IPv6
length minus extension headers.

Whether Wireshark should report a payload header field value longer than the
framing provides is a different issue. I think it should, as a PI_NOTICE at
minimum, but AFAIK, the same thing happens for IPv4, there are no validity
checks for the length other than being less than the minimum header size, so
this isn't specific to IPv6.
