+ Op-Code: PXENV_UNDI_ISR (0014h)

+ Output: PXENV_EXIT_SUCCESS or PXENV_EXIT_FAILURE must be returned in AX. The status field in
+ the parameter structure must be set to one of the values represented by the PXENV_STATUS_xxx
+ constants.
+ Description: This API function will be called at different levels of processing the interrupt. The FuncFlag field in
+ the parameter block indicates the operation to be performed for the call. This field is filled with the
+ status of that operation on return.
+ Note: Interrupt Service Routine Operation:
+ In this design the UNDI does not hook the interrupt for the Network Interface. Instead, the
+ application or the protocol driver hooks the interrupt and calls UNDI with the PXENV_UNDI_ISR
+ API call for interrupt verification (PXENV_UNDI_ISR_IN_START) and processing
+ (PXENV_UNDI_ISR_IN_PROCESS and PXENV_UNDI_ISR_GET_NEXT).
+ When the Network Interface HW generates an interrupt the protocol driver interrupt service
+ routine (ISR) gets control and takes care of the interrupt processing at the PIC level. The ISR then
+ calls the UNDI using the PXENV_UNDI_ISR API with the value PXENV_UNDI_ISR_IN_START for
+ the FuncFlag parameter. At this time UNDI must disable the interrupts at the Network Interface
+ level and read any status values required to further process the interrupt. UNDI must return as
+ quickly as possible with one of the two values, PXENV_UNDI_ISR_OUT_OURS or
+ PXENV_UNDI_ISR_OUT_NOT_OURS, for the parameter FuncFlag depending on whether the
+ interrupt was generated by this particular Network Interface or not.
+ If the value returned in FuncFlag is PXENV_UNDI_ISR_OUT_NOT_OURS, then the interrupt was
+ not generated by our NIC, and interrupt processing is complete.
+ If the value returned in FuncFlag is PXENV_UNDI_ISR_OUT_OURS, the protocol driver must start
+ a handler thread and send an end-of-interrupt (EOI) command to the PIC. Interrupt processing is
+ now complete.
+ The protocol driver strategy routine will call UNDI using this same API with FuncFlag equal to
+ PXENV_UNDI_ISR_IN_PROCESS. At this time UNDI must find the cause of this interrupt and
+ return the status in the FuncFlag. It first checks if there is a frame received and if so it returns the
+ first buffer pointer of that frame in the parameter block.
+ The protocol driver calls UNDI repeatedly with the FuncFlag equal to
+ PXENV_UNDI_ISR_IN_GET_NEXT to get all the buffers in a frame and also all the received
+ frames in the queue. On this call, UNDI must remember the previous buffer given to the protoco,l
+ remove it from the receive queue and recycle it. In case of a multi-buffered frame, if the previous
+ buffer is not the last buffer in the frame it must return the next buffer in the frame in the parameter
+ block. Otherwise it must return the first buffer in the next frame.
+ If there is no received frame pending to be processed, UNDI processes the transmit completes and
+ if there is no other interrupt status to be processed, UNDI re-enables the interrupt at the
+ NETWORK INTERFACE level and returns PXENV_UNDI_ISR_OUT_DONE in the FuncFlag.
+ IMPORTANT: It is possible for the protocol driver to be interrupted again while in the
+ strategy routine when the UNDI re-enables interrupts.

+ UNDI ISR
+ Op-Code: PXENV_UNDI_ISR (0014h)
+ Input: Far pointer to a PXENV_UNDI_ISR_T parameter structure that has been initialized by the caller.
+ Output: PXENV_EXIT_SUCCESS or PXENV_EXIT_FAILURE must be returned in AX. The status field in
+ the parameter structure must be set to one of the values represented by the PXENV_STATUS_xxx
+ constants.
+ Description: This API function will be called at different levels of processing the interrupt. The FuncFlag field in
+ the parameter block indicates the operation to be performed for the call. This field is filled with the
+ status of that operation on return.
+ Note: Interrupt Service Routine Operation:
+ In this design the UNDI does not hook the interrupt for the Network Interface. Instead, the
+ application or the protocol driver hooks the interrupt and calls UNDI with the PXENV_UNDI_ISR
+ API call for interrupt verification (PXENV_UNDI_ISR_IN_START) and processing
+ (PXENV_UNDI_ISR_IN_PROCESS and PXENV_UNDI_ISR_GET_NEXT).
+ When the Network Interface HW generates an interrupt the protocol driver interrupt service
+ routine (ISR) gets control and takes care of the interrupt processing at the PIC level. The ISR then
+ calls the UNDI using the PXENV_UNDI_ISR API with the value PXENV_UNDI_ISR_IN_START for
+ the FuncFlag parameter. At this time UNDI must disable the interrupts at the Network Interface
+ level and read any status values required to further process the interrupt. UNDI must return as
+ quickly as possible with one of the two values, PXENV_UNDI_ISR_OUT_OURS or
+ PXENV_UNDI_ISR_OUT_NOT_OURS, for the parameter FuncFlag depending on whether the
+ interrupt was generated by this particular Network Interface or not.
+ If the value returned in FuncFlag is PXENV_UNDI_ISR_OUT_NOT_OURS, then the interrupt was
+ not generated by our NIC, and interrupt processing is complete.
+ If the value returned in FuncFlag is PXENV_UNDI_ISR_OUT_OURS, the protocol driver must start
+ a handler thread and send an end-of-interrupt (EOI) command to the PIC. Interrupt processing is
+ now complete.
+ The protocol driver strategy routine will call UNDI using this same API with FuncFlag equal to
+ PXENV_UNDI_ISR_IN_PROCESS. At this time UNDI must find the cause of this interrupt and
+ return the status in the FuncFlag. It first checks if there is a frame received and if so it returns the
+ first buffer pointer of that frame in the parameter block.
+ The protocol driver calls UNDI repeatedly with the FuncFlag equal to
+ PXENV_UNDI_ISR_IN_GET_NEXT to get all the buffers in a frame and also all the received
+ frames in the queue. On this call, UNDI must remember the previous buffer given to the protoco,l
+ remove it from the receive queue and recycle it. In case of a multi-buffered frame, if the previous
+ buffer is not the last buffer in the frame it must return the next buffer in the frame in the parameter
+ block. Otherwise it must return the first buffer in the next frame.
+ If there is no received frame pending to be processed, UNDI processes the transmit completes and
+ if there is no other interrupt status to be processed, UNDI re-enables the interrupt at the
+ NETWORK INTERFACE level and returns PXENV_UNDI_ISR_OUT_DONE in the FuncFlag.
+ IMPORTANT: It is possible for the protocol driver to be interrupted again while in the
+ strategy routine when the UNDI re-enables interrupts.
