interfaces: T3090: migrate adjust-mss from "firewall options" to "interface" level
Getting rid of "set firewall options" and move it from: set firewall options interface ethX adjust-mss 1400 set firewall options interface ethX adjust-mss6 1400 to: set interfaces ethernet ethX ip adjust-mss 1400 set interfaces ethernet ethX ipv6 adjust-mss 1400 In addition add an extra option called clamp-mss-to-pmtu instead of a value.
