Hi,

When I look at a datapath ingress pipeline,
=========================
  table=3 (ls_in_pre_acl      ), priority=110  , match=(eth.dst == 1a:d2:77:6e:42:98), action=(next;)
  table=3 (ls_in_pre_acl      ), priority=0    , match=(1), action=(next;)
  table=4 (ls_in_pre_lb       ), priority=110  , match=(eth.dst == 1a:d2:77:6e:42:98), action=(next;)
  table=4 (ls_in_pre_lb       ), priority=110  , match=(nd || nd_rs || nd_ra || icmp4.type == 3 ||icmp6.type == 1 || (tcp && tcp.flags == 20)), action=(next;)
  table=4 (ls_in_pre_lb       ), priority=0    , match=(1), action=(next;)
  table=5 (ls_in_pre_stateful ), priority=100  , match=(reg0[0] == 1), action=(ct_next;)
  table=5 (ls_in_pre_stateful ), priority=0    , match=(1), action=(next;)
  table=6 (ls_in_acl          ), priority=34000, match=(eth.dst == 1a:d2:77:6e:42:98), action=(next;)
  table=6 (ls_in_acl          ), priority=0    , match=(1), action=(next;)
  table=7 (ls_in_qos_mark     ), priority=0    , match=(1), action=(next;)
  table=8 (ls_in_qos_meter    ), priority=0    , match=(1), action=(next;)
  table=9 (ls_in_lb           ), priority=0    , match=(1), action=(next;)
=========================
What's that MAC 1a:d2:77:6e:42:98? What's it for in acl and lb tables?
I can't find any port with that MAC.
This datapath is for a LS that is created from OpenStack.

Thanks!
Tony
