There are sligth differences between what the driver is doing now and what the spec say so this series tries to align the driver(s) with that. We also improve the "service" stack so that it is possible to run multiple DMA tunnels over a single XDomain connection, and update the two existing service drivers accordingly. We also decrease the control channel timeout when software based connection manager is used. The USB4 DROM spec adds a new product descriptor that includes the device and IDs instead of the generic entries in the Thunderbotl 1-3 DROMs. This series updates the driver to parse this descriptor too.
