IB/mad: Add final OPA MAD processing
For devices which support OPA MADs 1) Use previously defined SMP support functions. 2) Pass correct base version to ib_create_send_mad when processing OPA MADs. 3) Process out_mad_key_index returned by agents for a response. This is necessary because OPA SMP packets must carry a valid pkey. 4) Carry the correct segment size (OPA vs IBTA) of RMPP messages within ib_mad_recv_wc. 5) Handle variable length OPA MADs by: * Adjusting the 'fake' WC for locally routed SMP's to represent the proper incoming byte_len * out_mad_size is used from the local HCA agents 1) when sending agent responses on the wire 2) when passing responses through the local_completions function NOTE: wc.byte_len includes the GRH length and therefore is different from the in_mad_size specified to the local HCA agents. out_mad_size should _not_ include the GRH length as it is added Signed-off-by: Ira Weiny <ira.weiny@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
