selftests: forwarding: mirror_gre_vlan_bridge_1q: Unset rp_filter
The IP addresses of tunnel endpoint at H3 are set at the VLAN device
$h3.555. Therefore when test_gretap_untagged_egress() sets vlan 555 to
egress untagged at $swp3, $h3's rp_filter rejects these packets. The
test then spuriously fails.
Therefore turn off net.ipv4.conf.{all, $h3}.rp_filter.
