Hi Pravin, I'm actually seeing ubuntu kernels 3.13-4.2 becoming very unhappy with this patch when sending traffic through a vxlan tunnel with one endpoint in OVS in the host kernel, then the other vxlan endpoint as a native linux vxlan device sitting inside a namespace. This is something that works fine on master, and I think it was fine on earlier versions of the patch before the flow's actions were being freed (the fix for that revealed this problem). This test can be found by installing a recent iputils (for vxlan device creation via `ip link'), installing the module with this patch applied, and running `make check-kmod TESTSUITEFLAGS="-k vxlan"'. In practice I think that the minimal reproduction is as simple as adding a vxlan port to OVS when using a kernel < 4.3. I've got some example output below, but the actual errors vary quite a lot. Can you confirm whether you see the same sorts of problems?
