selftests: forwarding: mirror_gre_bridge_1q_lag: Ignore ARP

pmachata · davem330 · commit 2243cad9ffee · 2019-02-01T15:26:37.000-08:00
This test sets up mirroring such that it mirrors all overlay traffic.
That includes ARP, which causes occasional miscounts and spurious
failures. Ignore ARP explicitly to avoid these problems.
