Add ICAP_TSO6 capability for igb
It looks like this capability got dropped. Can you try with the attached patch?
(In reply to Stephen Hurd from comment #1) Patch worked, but I can not prove, that option is really working (in hardware) as event without option perf3 flat-outs at 990Mbit/s :-) A commit references this bug: Author: shurd Date: Thu Sep 20 20:06:45 UTC 2018 New revision: 338840 URL: https://svnweb.freebsd.org/changeset/base/338840 Log: Add IFCAP_TSO6 for igb It seems igb supports TSO6, but the capability got lost in the iflib update. Restore this capability.
