All=0A=
 I was looking into an issue I am seeing sporadically where I see LCAP link=
 state changes for no obvious reasons.=0A=
This is on 12.1-STABLE r354698 amd64 using Solarflare nics ( 7K and 8K card=
s). There are two ports in a LACP lagg with a few ( 10 - 30 ) =0A=
vlans on top of it.  As what appear to be random moments the LACP linkstate=
 flaps between the server and the switch.=0A=
It will flap for about 20 to 30 seconds and then resolve itself. =0A=
=0A=
I read this post from Oliver C about how net.link.ifqmaxlen can effect LACP=
 and LAGG but I dont understand how. =0A=
