[Test Case] For a PCIe device that supports 16 GT/s: $ cat /sys/devices/pci0000:80/0000:80:08.0/max_link_speed 16 GT/s [Fix] Cherry-pick an upstream commit that supports in-kernel decoding of 16 GT/s link speed [Regression Risk] Trivial fix that just adds an extra case in a switch statement w/ supporting #defines.
