Hmm, you are right, it seems that my second SAD entries are not used at all.
However I'm now running with net.inet.tcp.signature_verify_input = 0, because if I set it to 1
the BGP sessions to my other FreeBSD routers disconnect. (and that is running Quagga).
Am I the only one who sees this running Quagga? One difference probably is that I have both TCP-MD5 protected
sessions and ones that are not. And the not protected sessions fail if I start checking ingress tcp signatures.
