Log message:
pppoe(4): leverage if_hardmtu for RFC 4638 instead of parent if_mtu
Interfaces operate at their maximum supported packet size at all times,
independent of the software IP stack MTU.
Enforce MTU ceilings during PPPOESETPARMS and SIOCSIFMTU based on
if_hardmtu instead of the parent's software if_mtu. This allows pppoe(4)
devices to use "mtu 1500" without requiring manual MTU manipulation on
the physical parent interface. Update pppoe.4 to match.
