Two questions, to make sure we are clear on the type of genericity to achieve: - rules to process a packet depending on its ethertype, and process packets possibly coming from Eth ports and GRE ports, would need to be duplicated to test the Ethernet ethertype and the tunnel ethertype ? - what about other link layers than ethernet that may have an ethertype ? (thinking Infiniband at least for IP and ARP payloads, ATM too,...)
