[ fib daddr oif present => reg 1 ] So we can see from --debug=netlink this generates bytecode to check the presence. Same thing applies to: # exthdr hbh exists ip6 test-ip6 input [ exthdr load 1b @ 43 + 0 => reg 1 ] [ cmp eq reg 1 0x00000001 ] Instead, I'd suggest something like: [ exthdr 43 present => reg 1 ] [ cmp eq reg 1 0x00000001 ] You would need to send a follow up to amend test for 3/5, but that should be no problem.
