Looking through the 'iptables'-changelog and comparing the various
source codes seems to show that a "compat-part" of ebtables' was merged.
Since then it is developed as a (new) part of 'iptables':

'iptables' changelog:
...
ebtables-compat: [various entries]
...
Merge branch 'ebtables-compat'
...

This would be in context with the fact that only a few equivalent
source-files from the 'ebtables'-extensions-directory
(extensions/ebt_*.c) can be found in the corresponding
'iptables'-extensions-directory (extensions/libebt_*.c).

As I see it from here, the 'ebtables'-package *could* be obsolete, or
maybe *not*, depending on what purposes we need it for, or what
functions we want. Hard to tell for me, sorry.

@Jonatan:
Perhaps you could test 'iptables 1.6.0' with your actual branch - and
without 'ebtables', to see if 'ebtables' are really needed, especially
by 'libvrt'? Just an idea...

Best,
Matthias
