Ben,
Thank you for your response. I did some more digging and simplified
what I am doing. I can get it working fine with ovs 2.6.0 but with
2.11.0 I still get the error
"2019-03-21T12:00:50.563Z|00076|odp_util(handler49)|ERR|invalid
Ethertype 0 in flow key"
now I am getting it when I try to send a packet to the controller with
the following rule
"cookie=0xb90000b3443b96, duration=891.881s, table=0, n_packets=2073,
n_bytes=245802, priority=1333,in_port=input actions=CONTROLLER:65535"
If I write a rule to just pass all of the traffic to another port it
works fine. I thought maybe it has something to do with a miss match
between the kernel module and the ovs version I am using. I am using
debian, "SMP Debian 4.9.144-3.1", and I can not get the kernel module
to compile I get "error: too few arguments to function
'inet_fraq_find' ....
Any ideas on what to try next?
That's curious that a compile of the openvswitch kernel module fails on
4.9.144-3.1 because our travis build checker has support for all the way
up to 4.9.149 and it compiles just fine. I'm curious where you got this
kernel? If I could download and build it myself I could probably figure
out what the compile issue is.

Thank you,

You should not need to match on both labels to pop a single label.
If you use ofproto/trace for this packet (see ovs-vswitchd(8)), what
does it say?
