freebsd stable - Sep 2016 - 11.0 stuck on high network load

Hi,

Got some tips regarding this thread.

Some things you can try:

1) Compile kernel from projects/hps_head instead of your 11-stable?

2) Set net.inet.tcp.per_cpu_timers=1

If the system just hangs, it is pretty likely that the timers are going 
in a loop due to typical use after free.

Please keep me CC'ed, hence I'm not subscribed to @stable.

--HPS

How many difference from 11-stable?

Already. From 10.x, by manual MFC.
