thunderbolt: Limit USB3 bandwidth of certain Intel USB4 host routers

Browse source

[ Upstream commit f0a57dd33b ]

Current Intel USB4 host routers have hardware limitation that the USB3
bandwidth cannot go higher than 16376 Mb/s. Work this around by adding a
new quirk that limits the bandwidth for the affected host routers.
