[PATCH] PCI: MSI functionality broken on Serverworks GC chipset
MSI functionality is broken on the GC_LE x86 chipset that Serverworks developed and that is being used in various platforms today. Broadcom is going to push out to the kernel MSI enabled Gigabit drivers (in the very near future), and we would like to make sure that MSI does not get enabled on any platforms using the GC_LE chipset (device id 0x17). Following the AMD 8131 example, I am including a patch to disable MSI functionality when a GCNB_LE is detected. Please let me know if there are any issues with this. This is a permanent fix for this chipset, as the hardware will not be updated. Signed-off-by: Narendra Sankar <nsankar@broadcom.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
