From 9d18717790c43c904fabe9da7a4c6b2ebed2c4d8 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Fri, 6 Oct 2017 13:06:17 -0700 Subject: [PATCH] IB/core: Simplify sa_path_set_[sd]lid() calls Instead of making every caller convert the second argument of sa_path_set_slid() and sa_path_set_dlid() to big endian format, make these two functions accept LIDs in CPU endian format. This patch does not change any functionality.
