From a7fe7380f6b234f207a599c9ffbaae6c1a574634 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Thu, 22 Sep 2016 17:31:15 +0300 Subject: IB/ocrdma: Move user vendor structures This patch moves ocrdma 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. In addition, it changes types to be __uXX instead of uXX.
