Try to set "IndividualCalls=yes" in firewalld.conf.
with that set I now have more explicit errors inf firewalld logs:
2017-05-03 09:31:58 DEBUG2: <class 'firewall.core.ebtables.ebtables'>:

2017-05-03 09:32:00 ERROR: '/usr/sbin/ebtables -t broute -P BROUTING

I ran these broute commands manually and it returns returns;
# /usr/sbin/ebtables --concurrent -t broute -F
The kernel doesn't support the ebtables 'broute' table.
So I go check on a second host where firewalld keeps running
# lsmod |grep ebtab
ebtable_nat 12807 2
*ebtable_broute 12731 2 *
ebtable_filter 12827 2
ebtables 30905 3 ebtable_broute,ebtable_nat,ebtable_filter
bridge 119601 1 ebtable_broute
on the one where it fails
# lsmod |grep ebtab
ebtable_nat 12807 1
ebtable_filter 12827 3
ebtables 30905 2 ebtable_nat,ebtable_filter
indeed it lacks *ebtable_broute* , so :
# modprobe ebtable_broute
and now it works fine ;-) , thanks for the tip !
now why ebtable_broute isn't loaded at boot time is a mystery ,if you
have a idea ?
Thanks .
