--- Comment #22 from Marius Tomaschewski 2011-02-23 15:03:32 UTC ---
The patch does not work for me... Or more exactly:
the patch seems to be not the problem: the kernel seems to not to provide
the partial checksum info. None of the packets have the "aux->tp_status &
TP_STATUS_CSUMNOTREADY" flag set -- logging some debug info I get:

The code in the current kernel differs a lot from the
http://git.kernel.org/linus/8dc4194 patched version. AFAIS, some parts of it
are missing/removed.
Michal, the kernel does not provide any marked packets in the another domain;
can you take a look what is broken there?
