line 145 - line 157 are no longer relevant?

[xunjieli, 2016/09/12 17:17:43]

Might be also worth removing
URLRequestContextBuilder::set_quic_max_number_of_lossy_connections
and set_quic_packet_loss_threshold, since these two fields are no longer in the
HttpNetworkSession::Params.

Done.

[Ryan Hamilton, 2016/09/12 17:49:27]

Good point. Done
