-/*++
-
-Routine Description:
- This routine determines the operational state of the UNDI. It updates the state flags in the
- Command Descriptor Block based on information derived from the AdapterInfo instance data.
-
- To ensure the command has completed successfully, CdbPtr->StatCode will contain the result of
- the command execution.
-
- The CdbPtr->StatFlags will contain a STOPPED, STARTED, or INITIALIZED state once the command
- has successfully completed.
-
- Keep in mind the AdapterInfo->State is the active state of the adapter (based on software
- interrogation), and the CdbPtr->StateFlags is the passed back information that is reflected
- to the caller of the UNDI API.
-
-Arguments:
- CdbPtr - Pointer to the command descriptor block.
- AdapterInfo - Pointer to the NIC data structure information which the UNDI driver is layering on..

-UNDI_Start (
- IN PXE_CDB *CdbPtr,
- IN NIC_DATA_INSTANCE *AdapterInfo
- )
-/*++
-
-Routine Description:
- This routine is used to change the operational state of the UNDI from stopped to started.
- It will do this as long as the adapter's state is PXE_STATFLAGS_GET_STATE_STOPPED, otherwise
- the CdbPtr->StatFlags will reflect a command failure, and the CdbPtr->StatCode will reflect the
- UNDI as having already been started.
-
- This routine is modified to reflect the undi 1.1 specification changes. The
- changes in the spec are mainly in the callback routines, the new spec adds
- 3 more callbacks and a unique id.
- Since this UNDI supports both old and new undi specifications,
- The NIC's data structure is filled in with the callback routines (depending
- on the version) pointed to in the caller's CpbPtr. This seeds the Delay,
- Virt2Phys, Block, and Mem_IO for old and new versions and Map_Mem, UnMap_Mem
- and Sync_Mem routines and a unique id variable for the new version.
- This is the function which an external entity (SNP, O/S, etc) would call
- to provide it's I/O abstraction to the UNDI.
-
- It's final action is to change the AdapterInfo->State to PXE_STATFLAGS_GET_STATE_STARTED.
-
-Arguments:
- CdbPtr - Pointer to the command descriptor block.
- AdapterInfo - Pointer to the NIC data structure information which the UNDI driver is layering on..

-Routine Description:
- This routine is used to place a packet into the transmit queue. The data buffers given to

-
- When the packets are transmitted, a transmit complete interrupt is generated (if interrupts
- are disabled, the transmit interrupt status is still set and can be checked using the UNDI_Status
- command.
-
- Some implementations and adapters support transmitting multiple packets with one transmit
- command. If this feature is supported, the transmit CPBs can be linked in one transmit
- command.
-
- All UNDIs support fragmented frames, now all network devices or protocols do. If a fragmented
- frame CPB is given to UNDI and the network device does not support fragmented frames
- (see !PXE.Implementation flag), the UNDI will have to copy the fragments into a local buffer
