selftests: forwarding: mirror_gre_bridge_1q_lag: Flush neighbors
After one LAG slave is downed and another upped, it takes a while for the neighbor on a bridge to time out and get renegotiated. The test does prompt update of FDB entries by arpinging. But because the neighbor still references another address, offloading is not possible, and some packets may end up not being mirrored. To force the neighbor renegotiation, simply flush the neighbor table at the bridge. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
