Does this patch requires an explanation again? Well, here it goes:

This patch applies to 2.6.16.

This patch introduces the function ctnetlink_exp_dump_mask, that
correctly dumps the expectation mask. Such function uses the l3num value
from the expectation tuple that is a valid layer 3 protocol number.

The value of the l3num mask isn't dumped since it is meaningless from
the userspace side.
