From fad61ad4e755f5dd13c7702a87cd907207392534 Mon Sep 17 00:00:00 2001 From: Eli Cohen Date: Fri, 11 Mar 2016 22:58:36 +0200 Subject: IB/core: Add subnet prefix to port info The subnet prefix is a part of the port_info MAD returned and should be available at the ib_port_attr struct. We define it here and provide a default implementation in case the hardware driver does not provide one. The subnet prefix is required when creating the address vector to access the SA in networks where GRH must be used.
