- Changed log level from WARN to DEBUG for session-related messages in hidrpc.go to reduce noise during expected conditions.
- Adjusted logging in nmlite/interface.go to use DEBUG for non-critical DHCP lease messages and router solicitation failures.
- Improved link manager logging in nmlite/link/manager.go to differentiate between expected and persistent interface down states.
- Enhanced DHCP client logging in udhcpc/udhcpc.go to indicate non-fatal errors when calculating lease expiry.
Added a lot more logging detail to find the route bugs which was that the gateways were being added to the map with their IP and netmask, then looked for by only the IP, which meant we never removed them.
Replace log context additions that did .Str("foo", foo.String()) with .Stringer("foo", foo) so the conversion to string is lazy.
