From c546b2a3b6612a9fa09940a13844ef384683db6e Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Thu, 22 Sep 2016 17:31:16 +0300 Subject: IB/nes: Move user vendor structures This patch moves nes 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.
