Change default max_len to 65535 for controller action (#69)
Instead of 128.
65535 means that there is no buffering and that the full packet is sent
to the controller. This is actually the only value supported by OVS,
even though OVS will not reject other values. This can create confusion
as the flows will show `max_len=128`, but the controller will always
receive the full packet.
Another value for max_len can be explicitly provided using the new
`MaxLen` field in the `NXController` struct, but there should be no
reason to do so when using OVS.
