2019-10-16Do Duplicate Address Detection on permanent IPv6 addresses.Ghanan Gowripalan
This change adds support for Duplicate Address Detection on IPv6 addresses as defined by RFC 4862 section 5.4. Note, this change will not break existing uses of netstack as the default configuration for the stack options is set in such a way that DAD will not be performed. See `stack.Options` and `stack.NDPConfigurations` for more details. Tests: Tests to make sure that the DAD process properly resolves or fails. That is, tests make sure that DAD resolves only if: - No other node is performing DAD for the same address - No other node owns the same address PiperOrigin-RevId: 275189471
