LAG state becomes no-carrier even if there are members in LOWER_UP #600
Description
$ ip link show PortChannel0 ; ip link show Ethernet0 ; ip link show Ethernet4
38: PortChannel0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default

teamd min_ports configuration does not allow less than 75% of active members causing whole LAG to go down.
