This series fixes two issues in the bonding 802.3ad implementation
related to port state management and churn detection:
1. When disabling a port, we need to set AD_RX_PORT_DISABLED to ensure
proper state machine transitions, preventing ports from getting stuck
in AD_RX_CURRENT state.
2. The ad_churn_machine implementation is restructured to follow IEEE
802.1AX-2014 specifications correctly. The current implementation has
several issues: it doesn't transition to "none" state immediately when
synchronization is achieved, and can get stuck in churned state in
multi-aggregator scenarios.
3. Selftests are enhanced to validate both mux state machine and churn
state logic under aggregator selection and failover scenarios.
These changes ensure proper LACP state machine behavior and fix issues
where ports could remain in incorrect states during aggregator failover.
