Fix Thunderbolt-related issues in apple-gmux and vga_switcheroo: Patch [1/5] ("Recognize Thunderbolt devices") has already been subjected to a fair amount of scrutiny over at linux-pci@, I've submitted it 5 times total since May 2016. With luck it may be in ack-able shape now. Patch [2/5] amends apple-gmux to handle combined DP/Thunderbolt ports properly on newer MacBook Pros.

The wrong values are reported from pcie_bandwidth_available() which can cause problems for performance of eGPUs. This series overhauls Thunderbolt related device detection and uses the changes to change the behavior of pcie_bandwidth_available(). v2->v3: * Stop lumping all thunderbolt VSEC and USB4 devices together, introduce is_virtual_link instead * Drop unnecessary patches Mario
