--- Comment #12 from Jonas Liepuonius <thinker.lp at gmail.com> ---
Hello,

so I've encountered the same problem on FreeBSD 10.2 on XenServer 6.5.

Enabling pf basically shuts off my interfaces, pings go through but nothing
else.

I tried setting net.inet.tcp.tso=0 on boot in /etc/sysctl.conf and setting it
manually with sysctl but with no luck. ifconfig xn0 -tso -lro didn't help me
either.
