Not easily.  The system is currently running 12.1-RELEASE-p8.  I can, however,
test patches if you have a specific commit that may address the issue and works
w/ 12.1-RELEASE (or mostly applies to the source).

Currently using the out-of-tree intel-em-kmod driver on this platform, version
7.7.8 from Intel's download center.  The latest version in the ports tree is
7.7.5 and that one also exhibited issues w/ jumbo frames.  I ended up giving up
and went back to mtu 1500, and have not attempted jumbo frames on 7.7.8 yet.
