At least these tests (maybe more) fail with a limit this low:
  - selftests/net/forwarding/vxlan_symmetric.sh
  - selftests/net/forwarding/vxlan_symmetric_ipv6.sh
  - selftests/net/forwarding/vxlan_asymmetric.sh
  - selftests/net/forwarding/vxlan_asymmetric_ipv6.sh
  - selftests/net/test_bridge_backup_port.sh
  - selftests/net/test_vxlan_mdb.sh

Can in investigate what limit they need and whether their max is good
enough to avoid issues with KASAN?
