please let me summarize a problem regarding Linux multicast routing
in combination with L4 checksum offloading and own (locally produced)
multicast packets being forwarded.

Hi Cyril, thanks for the report, looks like nobody has immediate
feedback to share. Could you resend the patch in more usual form
so that it's easier to review and harder to ignore?

Thanks Jakub, I will do so. The patch I sent meant to be illustrative 
for the problem, but of course, the problem can be discussed around the 
patch.
