[ Upstream commit8955c1a329] As I want to test both DEVMAP and DEVMAP_HASH in XDP multicast redirect, I limited DEVMAP max entries to a small value for performace. When the test runs after amount of interface creating/deleting tests. The interface index will exceed the map max entries and xdp_redirect_multi will error out with "Get interfacesInterface index to large". Fix this issue by limit the tests in netns and specify the ifindex when creating interfaces.
