From 367d56f7b4d5ce61e883c64f81786c7a3ae88eea Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Tue, 4 Mar 2014 15:35:20 +0800 Subject: net/mlx4: Support shutdown() interface In kexec scenario, we failed to load the mlx4 driver in the second kernel because the ownership bit was hold by the first kernel without release correctly. The patch adds shutdown() interface so that the ownership can be released correctly in the first kernel. It also helps avoiding EEH error happened during boot stage of the second kernel because of undesired traffic, which can't be handled by hardware during that stage on Power platform.
