You will need to make sure you don't break backwards compatibility with
the ebtables userspace tool. ebtables.h::struct ebt_replace is a
structure used for communication between userspace and the kernel. It
has the member hook_entry defined like this:
struct ebt_entries __user *hook_entry[NF_BR_NUMHOOKS];
cheers,
Bart
