IB/hfi1: Define 16B Management Packets
Add 16B Management Packet definition. This optimized packet
format replaces the ib_other_headers and BTH with a source
and destination QP number.
To support these packets we introduce struct opa_16b_mgmt
into the struct hfi1_16b_header.
This packet format is only used for MAD packets using the
IB_OPCODE_UD_SEND_ONLY opcode on QP0/1.
The original 16B implementation failed to use 16B management
packets so now we add their definition.
