191  * ibmf_retrans_t data type is used to specify the maximum values
192  * of the retransmission parameters, number of retries,
193  * response time value, round trip travel time, and transaction timeout.
194  *
195  * The retries value must be provided by the client
196  * for all the transaction types enumerated by ibmf_trans_t.
197  * The retries value will be used to retry any section of
198  * the underlying transmission and reception protocol that
199  * are time bound by timers.
200  *
201  * The response time value must be specified for all transaction types except an
202  * unsequenced, non-RMPP send (see the table below).
203  * The response time value is the length of processing time for the
204  * responder to process the requested transaction, from the point of receiving
205  * the last request packet, to the point of returning the first response packet.
206  * This value is interpreted in microseconds.
207  * If the response time value is zero, an implementation default is used.
208  *
209  * The round trip time must be specified for all transaction types except an
210  * unsequenced, non-RMPP send (see the table below).
211  * The round trip travel time is the maximum time it should take a packet
212  * to travel from the requester to the responder and back to the requester.
213  * This value does not include the processing time at the responder.
214  * This value is interpreted in microseconds.
215  * If the round trip time value is zero, an implementation default is used.
216  *
217  * The transaction timeout should be specified for all transactions
218  * using RMPP to receive a message.
219  * Since, it is not possible for the client to know the size of the
220  * response, IBMF will calculate a reasonable transaction timeout after
221  * receiving the first RMPP data packet of the response at which time the
222  * size of the message will be known.  If this value is greater than the
223  * client's transaction timeout parameter the client's value will be used.
224  * If the client's transaction timeout parameter is 0 the calculated value will
225  * be used.
226  * This value is interpreted in microseconds.
227  * If the transaction timeout value is zero, an implementation default is used.
228  *

396  * the behavior supported via ibmf_impl_caps_t arg on successful return from
397  * ibmf_register(). ibmf_impl_caps_t arg points to a bit mask of the
398  * capabilities of the platform. If the implementation supports any
399  * P_Key and/or Q_Key value with IBMF_QP_HANDLE_DEFAULT, then
400  * IBMF_DEF_QP_HDL_P_KEY_ANY and/or IBMF_DEF_QP_HDL_Q_KEY_ANY will be set in
401  * ibmf_impl_caps_t.
402  *
403  * Some implementations support specifying any P_Key and Q_Key combination on
404  * a per-request basis when ibmf_qp_handle_t is set to an explicitly allocated
405  * qp handle (the client specifies the P_Key/Q_Key value in ibmf_addr_info_t
406  * argument). IBMA indicates this behavior by setting
407  * IBMF_NON_DEF_QP_HDL_P_KEY_ANY and/or IBMF_NON_DEF_QP_HDL_Q_KEY_ANY in the
408  * ibmf_impl_caps_t arg. In such an implementation, ibmf_modify_qp() does not
409  * change anything in the transport and always returns IBMF_SUCCESS.
410  *
411  * When the implementation supports IBMF_DEF_QP_HDL_P_KEY_ANY and/or
412  * IBMF_DEF_QP_HDL_Q_KEY_ANY, it may map IBMF_QP_HANDLE_DEFAULT to any qp
413  * number(s) supported by the
414  * underlying transport. The client can not not make any assumptions on this
415  * mapping nor can it query ibmf for the qp num being used with
416  * IBMF_QP_HANDLE_DEFAULT. There are cases where the client needs to have
417  * explicit control over the qp number being used by ibmf (eg., agent
418  * redirection). The client should explicitly allocate a qp using
419  * ibmf_alloc_qp() in such cases.
420  *
421  * Also, IBMF_QP_HANDLE_DEFAULT can only be used when the class of the MAD
422  * being sent using ibmf_msg_transport() is the same as the class the client
423  * registered for. If a client wishes to send a MAD class other than the
424  * one it registered for, it should explicitly allocate a qp and use that
425  * qp while sending MADs.
426  *
427  * If the implementation supports
428  * IBMF_DEF_QP_HDL_P_KEY_ANY/IBMF_DEF_QP_HDL_Q_KEY_ANY and/or
429  * IBMF_NON_DEF_QP_HDL_P_KEY_ANY/IBMF_NON_DEF_QP_HDL_Q_KEY_ANY, it is the
430  * implementation's responsibility to ensure that the
431  * requested P_Key and Q_Key can be used by, with in resource limitations,
432  * concurrent sends.
433  *
434  * Clients registering for classes that include an RMPP header in their
435  * MADs must set the IBMF_REG_FLAG_RMPP flag when registering with IBMF.
436  * This must be done regardless of whether the client intends to use
437  * the RMPP protocol or not. The flag is an indicator to IBMF of the
438  * presence of the RMPP header in the MAD.
439  *
440  * IBMF will always insure that receive buffer pointers are offsets into a
441  * single contiguous buffer of memory. The im_msgbufs_recv.im_bufs_mad_hdr,
442  * points to the start of the buffer. The other two pointers,
443  * im_msgbufs_recv.im_bufs_cl_hdr, and im_msgbufs_recv.im_bufs_cl_data,
444  * will point to class specific offsets within the buffer.
445  *
446  * Clients may provide a pointer to a callback function in the client_cb
447  * argument. Implementations of ibmf that require the client_cb to
448  * be specified should return IBMF_INVALID_ARG if the client_cb argument

651  * value other than 0x8001_0000 and/or P_Key value other than

667  * NOTE on notation: A message structure allocated by an ibmf_alloc_msg()

670  * it will be referred to as "message".
671  * NOTE: Rules for reusing an IBMF Message:
672  * Clients may reuse a Message, either provided by IBMF in an unsolicited
673  * request, or one obtained through the ibmf_alloc_msg() call, for a
674  * subsequent request from the client itself. The client may reuse a Message
675  * to avoid the overhead of allocating a new Message and new send buffers.
676  * To safely reuse Messages, the client must follow the rules listed below.
677  * 1) Using the receive buffers to send the message header and data:
678  * If the Message has been provided by IBMF in an unsolicited request,
679  * it will have its receive buffers already allocated and pointed to by
680  * im_msgbufs_recv pointers by IBMF. In such a case, a client may set
681  * the im_msgbufs_send pointers to the values in the im_msgbufs_recv
682  * thus reusing the buffer allocated by IBMF for the incoming Message.
683  * However, this may be done only when the request from the client is
684  * a non-sequenced operation i.e. IBMF_MSG_TRANS_FLAG_SEQ flag is not set.
685  * An attempt to reuse the receive buffer for any other operation will
686  * result in the failure of the ibmf_msg_transport() call with the error
687  * status IBMF_REQ_INVALID.
688  * 2) Providing send buffers to send the message header and data:
689  * If the client provides its own send buffers for the message header and data,
690  * the IBMF Message may be reused for both sequenced and non-sequenced
691  * transactions. Any receive buffers that were allocated by IBMF from a
692  * previous transaction, will be freed up once the Message is reused in an
693  * ibmf_msg_transport() call. New receive buffers will be provided by IBMF
694  * if the new transaction is a sequenced transaction.
695  *
696  * Input arguments:
697  *	Handle to the IBMF interface
698  *	IBMF QP handle (either allocated via ibmf_alloc_qp() or
699  *	    IBMF_QP_HANDLE_DEFAULT [see the NOTE above regarding MAD class])
700  *	Pointer to ibmf_msg_t to be sent

702  *	values to use during the transaction.

705  *	Argument to be passed when the callback is invoked
706  *	flags - set IBMF_MSG_TRANS_FLAG_RMPP if send should use RMPP

855  * and receive MADs up to the maximum MTU supported on the link
856  * connected to the chosen port.
857  *
