From e44ee2fd9845a86b0c7e8742672ae5ba6d7d34ee Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Thu, 22 Sep 2016 17:31:13 +0300 Subject: IB/cxgb4: Move user vendor structures This patch moves cxgb4 vendor's specific structures to common UAPI folder which will be visible to all consumers. These structures are used by user-space library driver (libcxgb4) and currently manually copied to that library. This move will allow cross-compile against these files and simplify introduction of vendor specific data.
