The forwarding selftests infrastructure makes it possible to run the individual tests on a purely software netdevices. Names of interfaces to run the test with can be passed as command line arguments to a test. lib.sh then creates veth pairs backing the interfaces if none exist in the system.
However, the tests need to recognize that they might be run on a soft device. Many mirror-to-gretap tests are buggy in this regard. This patch set aims to fix the problems in running mirror-to-gretap tests on veth devices. In patch #1, a service function is split out of setup_wait(). In patch #2, installing a trap is made optional. In patch #3, tc filters in several tests are tweaked to work with veth. In patch #4, the logic for waiting for neighbor is fixed for veth.
