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.
