            Bug ID: 252015
           Summary: Enabling LRO on network interfaces by default
                    considered harmful
           Product: Base System
           Version: Unspecified
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: rb@gid.co.uk

Just had no end of trouble getting a newly commissioned system to communica=
te
properly over ixl(4) interfaces. The problem turned out to be that LRO is
enabled by default, and interferes seriously with anything involving packet
forwarding. I'm not going to be the only one bitten by this so I propose th=
at
the default should be -lro.

Observed on 12.2-R but almost certainly applies to other versions and proba=
bly
to other interfaces as well.
