Default route changes unexpectedly #2 (was Re: kernel: arpresolve: can't allocate llinfo for 65.59.233.102)

[Nick Rogers]

I'm not sure. I have not explicitly enabled/disabled it. I am using
the GENERIC kernel from 9.1 plus PF+ALTQ.

# sysctl net.inet.flowtable.enable
sysctl: unknown oid 'net.inet.flowtable.enable'
# sysctl -a | grep flow
kern.sigqueue.overflow: 0
net.inet.tcp.reass.overflows: 0
net.inet6.ip6.auto_flowlabel: 1

uname -v
FreeBSD 9.1-RELEASE #0 r245436M: Mon Jan 14 16:34:21 EST 2013
root at fbsd_91:/usr/obj/usr/src/sys/CUSTOM

8.0 release notes say flowtable is enabled by default on amd64/i386.
So I presume it is enabled? I can't seem to find much information
about this for FreeBSD 9.x
