LACP / bonding: support configuration of minimum number of links
Closed, ResolvedPublicFEATURE REQUEST


Specifies the minimum number of links that must be active before
asserting carrier. It is similar to the Cisco EtherChannel min-links
feature. This allows setting the minimum number of member ports that
must be up (link-up state) before marking the bond device as up
(carrier on). This is useful for situations where higher level services
such as clustering want to ensure a minimum number of low bandwidth
links are active before switchover. This option only affect 802.3ad

The default value is 0. This will cause carrier to be asserted (for
802.3ad mode) whenever there is an active aggregator, regardless of the
number of available links in that aggregator. Note that, because an
aggregator cannot be active without at least one available link,
setting this option to 0 or to 1 has the exact same effect.
