From 2e08b5879e9244fa893fe09f5b887f72f4e6c29b Mon Sep 17 00:00:00 2001 From: Sean Hefty Date: Wed, 29 May 2013 10:09:26 -0700 Subject: [PATCH] IB/sa: Export function to pack a path record into wire format Allow converting from struct ib_sa_path_rec to the IB defined SA path record wire format. This will be used to report path data from the rdma cm into user space.
