[ovs-dev] [PATCH] xlate: don't add dummy eth header when doing recirc

In xlate_actions(), when packet comes from a L3 port and its packet_type is not Ethernet, then a dummy Ethernet header is added to the packet by setting flow->packet_type to Ethernet and zero out flow->dl_src and flow->dl_dst. This process should be avoided if packet is recirculated, i.e.

If we cannot talk to ovs-vswitchd process for some reason, e.g. it has terminated prematurely, we want to fail the test as soon as possible. Otherwise the test will likely fail later on due to ARP tables not being populated, which will make the troubleshooting the failure harder. Signed-off-by:
