Yes, thanks. It would have been more accurate to draw the comparison between ebtables and ebtables-nft, which is where the underlying problem arises. I was trying not to get too into the weeds with technical detail for the general user audience, who may not be particularly aware of the names for layer 2 filtering mechanisms, but I agree this wording is also mildly misleading as a result. Should I have said "Netfilter-based platforms (the successor to legacy IPTables)" instead, to differentiate it from Netfilter-based IPTables? -- Jeremy Stanley
