From 0b24e5ac93c2d0792ba8604e9f64e0b564d5f23e Mon Sep 17 00:00:00 2001 From: Majd Dibbiny Date: Sun, 17 Apr 2016 17:19:34 +0300 Subject: IB/core: Add extended device capability flags Since all the uverbs device_cap_flags are occupied, we need a place to expose more device capabilities. This patch adds a new 64 bit device_cap_flags_ex to expose new device capabilities. The lower 32 bits will be identical to the original device_cap_flags, The upper 32 bits will be new capabilities.
