* Revert "ebtables: use extrapositioned negation consistently"Phil Sutter2019-02-051-3/+3
| | | | | | | | | | | | | | | | | | | | | | | This reverts commit 5f508b76a0cebaf91965ffa678089222e2d47964. While attempts at unifying syntax between arp-, eb- and iptables-nft increase the opportunity for more code-sharing, they are problematic when it comes to compatibility. Accepting the old syntax on input helps, but due to the fact that neither arptables nor ebtables support --check command we must expect for users to test existence of a rule by comparing input with output. If that happens in a script, deviating from the old syntax in output has a high chance of breaking it. Therefore revert Florian's patch changing inversion character position in output and review the old code for consistency - the only thing changed on top of the actual revert is ebtables' own copy of print_iface() to make it adhere to the intrapositioned negation scheme used throughout ebtables. Added extension tests by the reverted commit have been kept. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Florian Westphal <fw@strlen.de>
* ebtables: use extrapositioned negation consistentlyFlorian Westphal2018-11-121-3/+5
| | | | | | | | | | | | | | in the iptables universe, we enforce extrapositioned negation: ! -i foo "-i ! foo" is not even supported anymore. At least make sure that ebtables prints the former syntax everywhere as well so we don't have a mix of both ways. Parsing of --option ! 42 will still work for backwards compat reasons.
