Comment 3 Mark Linimon freebsd_committer freebsd_triage 2015-11-12 07:44:30 UTC 
Reassign to erj@ for triage.  To submitter: is this issue still relevant?
Comment 4 Eric Joyner freebsd_committer freebsd_triage 2017-12-18 20:53:20 UTC 
FreeBSD 8 and its point releases have been EOL'd. If the submitter still needs jumbo frames, he/she should update to FreeBSD 10 or 11 and submit a new bug if it doesn't work.
