From af1ba291c5e498973cc325c501dd8da80b234571 Mon Sep 17 00:00:00 2001 From: Artemy Kovalyov Date: Fri, 17 Jun 2016 15:33:32 +0300 Subject: {net, IB}/mlx5: Refactor internal SRQ API Currently, the SRQ API uses the obsolete mlx5_*_srq_mbox_{in,out} structs which limit the ability to pass the SRQ attributes between net and IB parts of the driver. This patch changes the SRQ API so as to use auto-generated structs and provides a better way to pass attributes which will be in use by coming features.
