From: Jarod Wilson Date: Mon, 19 Oct 2015 15:52:04 +0000 (-0400) Subject: igb: improve handling of disconnected adapters X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7b06a6909555ffb0140733cc4420222604140b27;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git igb: improve handling of disconnected adapters Clean up array_rd32 so that it uses igb_rd32 the same as rd32, per the suggestion of Alexander Duyck, and use io_addr in more places, so that we don't have the need to call E1000_REMOVED (which simply looks for a null hw_addr) nearly as much.
