extensions: Add string filter to ebtables
This patch is part of a proposal to add a string filter to
ebtables, which would be similar to the string filter in
iptables.
Like iptables, the ebtables filter uses the xt_string module,
however some modifications have been made for this to work
correctly.
Currently ebtables assumes that the revision number of all match
modules is 0. The xt_string module doesn't register a match with
revision 0 so the solution is to modify ebtables to allow
extensions to specify a revision number, similar to iptables.
This gets passed down to the kernel, which is then able to find
the match module correctly.
