From da2dfaa3a35cb5b68fc6ab2e442339de03cacd09 Mon Sep 17 00:00:00 2001 From: Ira Weiny Date: Sat, 6 Jun 2015 14:38:28 -0400 Subject: [PATCH] IB/mad: Support alternate Base Versions when creating MADs In preparation to support the new OPA MAD Base version, add a base version parameter to ib_create_send_mad and set it to IB_MGMT_BASE_VERSION for current users. Definition of the new base version and it's processing will occur in later patches.
