From fb532d6a79b96a4c8f678024d7ed3549ff0ca916 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Tue, 23 Feb 2016 10:25:25 +0200 Subject: IB/{core, ulp} Support above 32 possible device capability flags The old bitwise device_cap_flags variable was limited to u32 which has all bits already defined. In order to overcome it, we converted device_cap_flags variable to be u64 type.
