From 9ce28a20eec551cfc032c87cd31a05c14d11155d Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Thu, 22 Sep 2016 17:31:14 +0300 Subject: IB/mlx4: Move user vendor structures This patch moves mlx4 vendor's specific structures to common UAPI folder which will be visible to all consumers. These structures are used by user-space library driver (libmlx4) and currently manually copied to that library. This move will allow cross-compile against these files and simplify introduction of vendor specific data.
