/* Dump out chain names first,
* thereby preventing dependency conflicts */
The initial problem was 'ebtables-save -c' printing iptables-style counters but at the same time not disabling ebtables-style counter output (which was even printed in wrong format for ebtables-save). The code around counter output was complicated enough to motivate a larger rework: * Make FMT_C_COUNTS indicate the appended counter style for ebtables. * Use FMT_EBT_SAVE to distinguish between '-c' style counters and the legacy pcnt/bcnt ones. Consequently, ebtables-save sets format to: FMT_NOCOUNTS - for no counters FMT_EBT_SAVE - for iptables-style counters FMT_EBT_SAVE | FMT_C_COUNTS - for '-c' style counters For regular ebtables, list_rules() always sets FMT_C_COUNTS (iptables-style counters are never used there) and FMT_NOCOUNTS if no counters are requested. The big plus is if neither FMT_NOCOUNTS nor FMT_C_COUNTS is set, iptables-style counters are to be printed - both in iptables and ebtables. This allows to drop the ebtables-specific 'save_counters' callback.
