Subject: [PATCHv2 net 1/3] bonding: update LACP activity flag after setting lacp_active
The port's actor_oper_port_state activity flag should be updated immediately
after changing the lacp_active option to reflect the current mode correctly.
Fixes: 3a755cd8b7c6 ("bonding: add new option lacp_active")
Signed-off-by: Hangbin Liu <liuhangbin@...il.com>
