From db58540b021a17e0ede64f761b740556d77f1679 Mon Sep 17 00:00:00 2001 From: Dasaratharaman Chandramouli Date: Thu, 8 Jun 2017 13:37:48 -0400 Subject: [PATCH] IB/core: Change port_attr.sm_lid from 16 to 32 bits sm_lid field in struct ib_port_attr is increased to 32 bits. This enables core components to use larger LIDs if needed. The user ABI is unchanged and return 16 bit values when queried.
