DescriptionLabel IPv6 reachability checks in NetLog
Chrome's internal DNS resolver checks whether the host currently has
global IPv6 connectivity by creating a socket connected to Google Public
DNS' IPv6 address. These show up in the NetLog as UDP_SOCKET objects
with a source dependency of the HOST_RESOLVER_IMPL_REQUEST.
This change adds an explicit IPV6_REACHABILITY_CHECK source type that
will show up instead, to clarify the purpose of the UDP sockets.
(Note that no packets are actually sent as a result of the checks; UDP
doesn't need to send any packets to connect, and the HostResolverImpl
doesn't send any data over the socket explicitly.)
