bonding: 3ad: add lacp_strict configuration knob
[ Upstream commit 32b0b8953343eaceaa816a9ead3b6bb66355c64e ]
When an 802.3ad (LACP) bonding interface has no slaves in the
collecting/distributing state, the bonding master still reports
carrier as up as long as at least 'min_links' slaves have carrier.
In this situation, only one slave is effectively used for TX/RX,
while traffic received on other slaves is dropped. Upper-layer
daemons therefore consider the interface operational, even though
traffic may be blackholed if the lack of LACP negotiation means
the partner is not ready to deal with traffic.
Introduce a configuration knob to control this behavior. It allows
the bonding master to assert carrier only when at least 'min_links'
slaves are in Collecting_Distributing state.
The default mode preserves the existing behavior. This patch only
introduces the knob; its behavior is implemented in the subsequent
commit.
