From a42fb351ca1f340f8307468be765e3f77ddedda9 Mon Sep 17 00:00:00 2001 From: Knuth Posern Date: Sun, 20 Sep 2015 21:25:22 +0200 Subject: thunderbolt: Allow loading of module on recent Apple MacBooks with thunderbolt 2 controller The pci device ids listed in the thunderbolt driver are to restrictive, which prevents the driver from being loaded on recent Apple MacBooks using a thunderbolt 2 controller. In particular this prevented any hot-plugging functionality for thunderbolt based ethernet dongles (i.e. Apples thunderbolt gigabit ethernet broadcom tg3 based dongle Model A1433 EMC 2590). Changing the subvendor and subdevice to PCI_ANY_ID the thunderbolt driver loads and binds to the pci device 07:00.0 System peripheral: Intel Corporation Device 156c which is the thunderbolt 2 controller on the MacBookPro12,1. Successfully tested on MacBookPro12,1. With the patch the thunderbolt module gets now loaded on boot. And it provides hot-plugging support both for a cold-plugged and a warm-plugged ethernet dongle.
