In most cases the response packet is lost because the router in question was disconnected by the user. Resending the control packet in that case just adds unnecessary delays, so disable that for intra-domain control packets. For inter-domain (XDomain) packets we continue retrying. This also aligns the driver better what the Intel connection manager firmware is doing.
