The mirroring tests are currently run in a skip_hw and optionally a skip_sw mode. The former tests the SW datapath, the latter the HW datapath, if available. In order to be able to test SW datapath on HW loopbacks, traps are installed on ingress to get traffic from the HW datapath to the SW one. This adds an unnecessary complexity when it would be much simpler to just use a veth-based topology to test the SW datapath. Thus drop all the code that supports this dual testing.

# Test for "tc action mirred egress mirror" when the device to mirror to is a
|
|
# gretap or ip6gretap netdevice. Expect that the packets come out encapsulated,
|
|
# and another gretap / ip6gretap netdevice is then capable of decapsulating the
|
|
# traffic. Test that the payload is what is expected (ICMP ping request or
|
|
# reply, depending on test).
