* commands the adapter to transition an invalid STag to the
* valid state without changing any of its other attributes.
* The Validate-STag-/Validate-STag-Response- messages
* allow a Neterion-proprietary ability to revalidate an invalid
* STag without changing any of its attributes or its PBL. This
* is expected to be useful in situations where an STag is

* Invalidate Local Tag Request message is used by the host to
* invalidate a local STAG. This message provides an alternative
* route for the normal TOWI based STAG Invalidation. It allows a
* kernel mode process to invalidate an STAG without writing
* a TOWI.

* (valid) MR. This message provides an alternative to the TOWI
* based implementation allowing the path be used for MW binding
* @VXGE_HAL_MSG_TYPE_STAG_BIND_MW_RESP: This upward message
* communicates to the host the success or failure of the
* corresponding STAG Bind MW Request message.
* @VXGE_HAL_MSG_TYPE_STAG_FAST_REGISTER_NSMR_REQ: The STAG Fast
* Register NSMR Request provides an alternative way to fast
* register an NSMR instead of going to the TOWI path.

* Request would be used to change the NCE entry associated
* with a particular bytestream or iWARP session. This message
* could be used to change the NCE of a group of sessions if a
* particular path went down and need to be replaced by a new path
* The host is responsible for tracking the mapping of sessions to
* NCEs so that when de-allocating an NCE it does not de-allocate
* on that is still in use by a particular session.

* for timer purposes and transferring messages to the RPE but it
* contains no session context.
* @VXGE_HAL_MSG_TYPE_LRO_OPEN_RESP:The LRO Open Response message
* is sent in response to a LRO Open Request message to
* indicate that the LRO session has been opened.
* @VXGE_HAL_MSG_TYPE_LRO_END_CLASSIF_REQ:The LRO End
* Classification Request is sent by the host before the LRO
* Delete Request to tell the adapter to stop steering Rx
* frames from that session into the LRO path. The host would
* later call LRO Delete Request . Separating these two calls
* allows enough time to pass so that frames already in the FB can
* be drained out, thereby avoiding the need for frame reversion.
* @VXGE_HAL_MSG_TYPE_LRO_END_CLASSIF_RESP:The LRO End
* Classification Response message is sent in response to a
* LRO End Classification Request message to indicate that
* classification has been stopped for the LRO session and the
* host can proceed with deleting the LRO session.
* @VXGE_HAL_MSG_TYPE_LRO_DELETE_REQ:The LRO Delete Request
* message is sent by the host to delete a LRO session on the
* adapter.It might be possible in the future to replace this
* message and the TCP Delete Request with a single common
* message since there doesn't seem to be any difference between
* the two anymore.
* @VXGE_HAL_MSG_TYPE_LRO_DELETE_RESP:The LRO Delete Response
* message is sent in response to a LRO Delete Request message
* to indicate that the LRO session has been deleted.
* @VXGE_HAL_MSG_TYPE_LRO_SESSION_CANDIDATE_NOTIF:This msg
* indicates to the host that the adapter's autoLRO feature has
* identified a candidate LRO session. No response from the host
* is required. (If the host did decide to act on this information
* from the adapter, the host would use the usual LRO Open Request
* ).
* @VXGE_HAL_MSG_TYPE_SPDM_OPEN_REQ:The SPDM Open Request message
* is sent by the host to open an SPDM connection on the adapter.
* There is no RPE or PE context for an SPDM session. The ONE is
* not involved in this type of classification.
* @VXGE_HAL_MSG_TYPE_SPDM_OPEN_RESP:The SPDM Open Response
* message is sent in response to a SPDM Open Request message
* to indicate the status of creating the SPDM session.
* @VXGE_HAL_MSG_TYPE_SPDM_DELETE_REQ:The SPDM Delete Request
* message is sent by the host to delete an SPDM session on the
* adapter. It might be possible in the future to replace this
* message and the LRO/TCP Delete Request with a single common
* message since there doesn't seem to be any difference between
* the two anymore.
* @VXGE_HAL_MSG_TYPE_SPDM_DELETE_RESP:The SPDM Delete Response
* message is sent in response to a SPDM Delete Request message
* to indicate that the SPDM session has been deleted.
* @VXGE_HAL_MSG_TYPE_SESSION_EVENT_NOTIF:The Session Event
* Notification message is an unsolicited message from the
* adapter used to inform the host about an unexpected condition
* on a bytestream or iWARP session.
* @VXGE_HAL_MSG_TYPE_SESSION_QUERY_REQ:The Session Query Request
* message is sent by the host to query the attributes of an
* existing offloaded session. This message may be used to query
* the attributes of an SPDM, LRO, bytestream or iWARP session.
* Initially this will be a single message used for all purposes.
* In the future this may be split up into multiple messages
* allowing the user to query the pecific context for an SPDM,
* LRO, iWARP, or bytestream session.
* @VXGE_HAL_MSG_TYPE_SESSION_QUERY_RESP:The Session Query Response
* message is sent in response to a Session Query Request
* message to return the attributes associated with the specified
* session
* @VXGE_HAL_MSG_TYPE_SESSION_RETURN_IN_PROG_WQES: This message is
* generated by the adapter during deletion of a session to return
* any WQEs that may be in the in-progress list for the session.If
* a WQE is in the in-progress list it is owned by the session and
* cannot be returned to the head of WQE list for an SRQ because
* of ordering issues. Therefore, it must be returned to the host
* at which point the host may choose to destroy the resource or
* simply re-post the WQE for re-use.
* @VXGE_HAL_MSG_TYPE_SESSION_FRAME_WRITE:The Frame Write message is
* generated by the adapter in order to send certain frames to the
* host via the path instead of the normal path. Frames will be
* sent to the host under the following conditions:
* 1) mis-aligned frames that the adapter cannot place
* 2) during debugging to look at the contents of the frame
* In addition to this,a RDMA terminate message will also be sent
* via a message but in this case it will be sent in a TCP RDMA
* Terminate Received message. Frames arriving in the will
* not have markers stripped. Instead the host will be responsible
* for stripping markers and taking appropriate action on the
* received frame.
* @VXGE_HAL_MSG_TYPE_SQ_CREATE_REQ: This is HAL private message for.
* SQ create. Never used.
* @VXGE_HAL_MSG_TYPE_SQ_CREATE_RESP: This is HAL private message
* for SQ create response. This is reported to clients by HAL.
* @VXGE_HAL_MSG_TYPE_SQ_DELETE_REQ: This is HAL private message for.
* SQ delete. Never used.
* @VXGE_HAL_MSG_TYPE_SQ_DELETE_RESP:This is HAL private message
* for SQ delete response. This is reported to clients by HAL.
