Thanks. The MTU is auto negotiated to 1492. max-mss is 1440 in pf. I don't think OpenBSD has netisr or an equivalent since I don't see anything in the sysctl list, but it was implemented in FreeBSD and has allowed a number of people to fully saturate the mutli-gig symmetrical connections offered by newer ISPs using PPPoE. I should add *ON mutli-core/slower speed CPUs".
