Log message:
Use TSO and LRO on the loopback interface to transfer TCP faster.
If tcplro is activated on lo(4), ignore the MTU with TCP packets.
They are passed along with the information that they have to be
chopped in case they are forwarded later. New netstat(1) counter
shows that software LRO is in effect. The feature is currently
turned off by default.
