+Subject: [PATCH] teamd: do not process lacpdu before the port ifinfo is set
+
+Now the port ifinfo will be set in obj_input_newlink when a RTM_NEWLINK
+event is received.
+
+But when a port is being added, if a lacpdu gets received on this port
+before the RTM_NEWLINK event, lacpdu_recv will process the packet with
+incorrect port ifinfo.
+
+In Patrick's case, as ifinfo->master_ifindex was 0, it would skip this
+port in teamd_for_each_tdport, which caused lacp_port->agg_lead not to
+be updated in lacp_switch_agg_lead. Later the lacp_port actor would go
+to a unexpected state.
+
+This patch is to avoid it by checking teamd_port_present in lacpdu_recv
+so that it would not process lacpdu before the port ifinfo is set.
