From a85fb3383340b417132e5731f9694840660887cb Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Thu, 22 Sep 2016 17:31:12 +0300 Subject: IB/cxgb3: Move user vendor structures This patch moves cxgb3 vendor's specific structures to common UAPI folder which will be visible to all consumers. These structures are used by user-space library driver (libcxgb3) and currently manually copied to that library. This move will allow cross-compile against these files and simplify introduction of vendor specific data.
