Backport of
jpirko/libteam@54f137c
According to 6.4.15 of IEEE 802.1AX-2014, Figure 6-22, the state that the
port is selected moves MUX state from DETACHED to ATTACHED.
But ATTACHED state does not mean that the port can send and receive user
frames. COLLECTING_DISTRIBUTION state is the state that the port can send
and receive user frames. To move MUX state from ATTACHED to
COLLECTING_DISTRIBUTION, the partner state should be sync as well as the
port selected.
In function lacp_port_actor_update(), only INFO_STATE_SYNCHRONIZATION
should be set to the actor.state when the port is selected.
INFO_STATE_COLLECTING and INFO_STATE_DISTRIBUTING should be set to false
with ATTACHED mode and set to true when INFO_STATE_SYNCHRONIZATION of
partner.state is set.
In function lacp_port_should_be_{enabled, disabled}(), we also need to
check the INFO_STATE_SYNCHRONIZATION bit of partner.state.
