From: Bruce Richardson Date: Fri, 15 May 2015 15:56:46 +0000 (+0100) Subject: drivers: create new directory X-Git-Tag: spdx-start~9174 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=980ed498eb1dd0;p=dpdk.git drivers: create new directory Add a new top-level "drivers" directory to which all PMDs will be moved for easier maintenance of both lib folder and drivers themselves. This new directory is a dependency of all the apps in the app folder, so the makefiles for each app are updated. To the new top-level directory add a "net" subdirectory to classify more specifically our existing PMDs as ethernet drivers Signed-off-by: Bruce Richardson Acked-by: John McNamara [Thomas: fix dependencies and merge several patches] Acked-by: Thomas Monjalon --- diff --git a/GNUmakefile b/GNUmakefile index d04c20b605..b59e4b6ee9 100644 --- a/GNUmakefile +++ b/GNUmakefile @@ -1,6 +1,6 @@ # BSD LICENSE # -# Copyright(c) 2010-2014 Intel Corporation.
