[PATCH 13/20] IB/mad: Add base version parameter to ib_create_send_mad

ira.weiny-ral2JQCrhuEAvxtiuMwx3w
2015-01-12T17:11:05Z

From: Ira Weiny <ira.weiny-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

In preparation to support the new OPA MAD Base version, add a base version
parameter 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.
