From 794b799086d930a4398a7c72fc441b3406108501 Mon Sep 17 00:00:00 2001 From: Xiao Wang Date: Fri, 19 Feb 2016 19:06:59 +0800 Subject: [PATCH] fm10k/base: allow removal of slot appropriate check The Linux Kernel provides the OS a call "pcie_get_minimum_link" which can crawl the PCIe tree and determine the actual minimum link speed of a device which is a more general check than provided by is_slot_appropriate. Thus, the kernel driver does not use or want the is_slot_appropriate function call. Add a NO_IS_SLOT_APPROPRIATE_CHECK definition which can be defined to remove the code. If left undefined (the default) then the code will all be active and no driver changes should be necessary.
