ugly_patch_exposing_64-bit_counters

This patch at least exposes exposes 64-bit interface counters for vlan
children, althrouhg the speed of aggregate interface itself is still being
calculated by LACP code.

Interface speed for LACP aggretated LAGGs is calculated in
sys/net/ieee8023ad_lacp.c When the state of LACP interface changes VLAN
children should also be made aware of this. Maybe someone will correct this by
reinitializing valuse for LACP aggregate in right way by calling
sys/net/ieee8023ad_lacp.c instead of comment  /* LACP updates if_baudrate
itself */.

At present (11.1-PRERELEASE) this bug refers only to VLAN interfaces created
from startup scripts on the top of LACP LAGGs. 
When the VLAN interface is created manually after the parent LACP LAGG is up,
the speed reported by the interface reflects the speed of parent LAGG, also the
64-bit counters are present for such VLAN interface.

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.

Please show output of "ifconfig -m" command for physical interface, for lagg
and for vlan over lagg.

I confirm aforementioned behavior for 11-STABLE r318137. 64 bit counters are
reported, but not working correctly for VLAN interfaces created on LAGG,
although they work fine for interfaces belonging to that LAGG. Maybe the issue
is related to incorrect speed reported by this VLAN interfaces (10Mbps).

I am stuck on this version of FreeBSD because of this unresolved bug:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219453 so, I am not able to
test it on latest 11.1-BETA.

Please re-test this using any supported FreeBSD version (e.g. 10.3+ or 11). It
should work here now.
