Brian,

I'm using mip6d from git://www.umip.org/git/umip.git commit id
d1c240f3deb690af902ce1ff128780551ff6141c.  Is that the correct version
to use?  Looking at the kernel code again, the checksum error should
have been caught in icmpv6_rcv.  There are probably something wrong
with my setup.  I'll dig around a bit more.

Tests 5-3-1 to 5-3-6 also failed for me.   Did they pass for you?

Steve
