FreeBSD Networkers,

We are seeing LACP port flapping on our FreeBSD 10.4/12.1 systems under dif=
ferent conditions.

Can someone explain or point me to the information on how to queue the LACP=
 packets to
a higher priority queue ?

We are using the Chelsio T580-LP-CR adapter/cxgbe driver.  The Cheslio NICs=
 have 8 TX/RX queues each,
but I don't know how to explicitly put the LACP packets in the higher prior=
ity TX queue.

I've read about PF/ALTQ and think this may be overkill our needs, and was w=
ondering if there
was a simpler method.

Thanks
Greg
