selftests: fib_nexthops: Test cleanup of FDB entries following nexthop deletion (7a5e9d84) · Commits · 戴 / test

Commit ("vxlan: support for nexthop notifiers") registered a listener in the VXLAN driver to the nexthop notification chain. Its purpose is to cleanup FDB entries that use a nexthop that is being deleted. Test that such FDB entries are removed when the nexthop group that they use is deleted. Test that entries are not deleted when a single nexthop in the group is deleted. Signed-off-by:
