From 486f60954c71c5ce42341ed02cf804dda1c1bcc5 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Thu, 22 Sep 2016 17:31:17 +0300 Subject: IB/mthca: Move user vendor structures This patch moves mthca vendor's specific structures to common UAPI folder which will be visible to all consumers. These structures are used by user-space library driver (libmthca) and currently manually copied to that library. This move will allow cross-compile against these files and simplify introduction of vendor specific data.
