Resolves https://github.com/sigp/lighthouse/issues/2602 ## Issue Addressed https://github.com/sigp/lighthouse/pull/2749#issue-1037552417 > ## Open TODO > Add tests for boot_node flags `enable-enr-auto-update` and `disable-packet-filter`. They end up in [Discv5Config](https://github.com/mooori/lighthouse/blob/9ed2cba6bc3e41f08207cb0eeaf9e4aee40d05dd/boot_node/src/config.rs#L29), which doesn't support serde (de)serialization. ## Proposed Changes - Added tests for flags `enable-enr-auto-update` and `disable-packet-filter` - Instead of (de)serialize Discv5Config, added the two fields copied from Discv5Config to BootNodeConfigSerialization.
