[ovs-discuss] Replacing IPsec-GRE tunnel ports

I managed to test the setup on two Ubuntu 15.04 machines, with their
default setup - kernel 3.19, OVS 2.3.2, with Racoon 0.82 and Strongswan

I got 200-300 Mbit between VMs (OVS, ipsec, VLAN tag), and I expect that to
be ok.

Then, I updated the kernel to 4.1.6, and - guess what? I get 1.5-1.8 Mbps.
So it looks like a kernel issue. Kernel 4.2 from Trusty does the same
thing. Only in the Xenial 4.4 kernel I got back to 200-300 Mbit.
