This test has been done on the spare machine, which had been setup to test
mentioned Bug 219453. The machine is currently running fresh FreeBSD 11.1-BETA2
#0 r319996.

Ifconig -m doesn't show interface speed for this devices. Output is limited to
physical interfaces belonging to the LAGG, LAGG interface itself and one child
VLAN. IP addresses are not shown as irrelevant.

For this system bsmnmpwalk shows 64-bit counters present for only 3 interfaces:
