Cause: Problems with NetworkPolicy in 4.6.9
Consequence: After upgrading to 4.6.9 customers who have any NetworkPolicies in their clusters might experience network connectivity problems (even in namespaces that don't have NetworkPolicies).
Fix: Reverted several performance-related fixes that had been made to the NetworkPolicy code.
Result: NetworkPolicy works again, though without the performance improvements that had shipped in 4.6.9.
