From 57520751445b837c20a8e658e3dae3a7e7ddf45c Mon Sep 17 00:00:00 2001 From: Dasaratharaman Chandramouli Date: Thu, 27 Apr 2017 19:06:01 -0400 Subject: IB/SA: Add OPA path record type Add opa_sa_path_rec to sa_path_rec data structure. The 'type' field in sa_path_rec identifies the type of the path record.
