This change has caused a regression. Simple ip monitor command now fails.

$ ip monitor
Failed to add stats group to list

The failure is from setsockopt() returning -EINVAL

Using git bisect this patch is identified as the cause.
Please fix ASAP or will revert from next release and maybe even make
a point release to remove it.
