*AdapterInfo
70 This routine determines the operational state of the UNDI. It updates the state flags in the
71 Command Descriptor Block based on information derived from the AdapterInfo instance data.
73 To ensure the command has completed successfully, CdbPtr->StatCode will contain the result of
74 the command execution.
76 The CdbPtr->StatFlags will contain a STOPPED, STARTED, or INITIALIZED state once the command
77 has successfully completed.
79 Keep in mind the AdapterInfo->State is the active state of the adapter (based on software
80 interrogation), and the CdbPtr->StateFlags is the passed back information that is reflected
81 to the caller of the UNDI API.

*AdapterInfo
104 This routine is used to change the operational state of the UNDI from stopped to started.
105 It will do this as long as the adapter's state is PXE_STATFLAGS_GET_STATE_STOPPED, otherwise
106 the CdbPtr->StatFlags will reflect a command failure, and the CdbPtr->StatCode will reflect the
107 UNDI as having already been started.
109 This routine is modified to reflect the undi 1.1 specification changes. The
110 changes in the spec are mainly in the callback routines, the new spec adds
111 3 more callbacks and a unique id.
112 Since this UNDI supports both old and new undi specifications,
113 The NIC's data structure is filled in with the callback routines (depending
114 on the version) pointed to in the caller's CpbPtr. This seeds the Delay,
115 Virt2Phys, Block, and Mem_IO for old and new versions and Map_Mem, UnMap_Mem
116 and Sync_Mem routines and a unique id variable for the new version.
117 This is the function which an external entity (SNP, O/S, etc) would call
118 to provide it's I/O abstraction to the UNDI.
120 It's final action is to change the AdapterInfo->State to PXE_STATFLAGS_GET_STATE_STARTED.

1223 When the packets are transmitted, a transmit complete interrupt is generated (if interrupts
1224 are disabled, the transmit interrupt status is still set and can be checked using the UNDI_Status
1227 Some implementations and adapters support transmitting multiple packets with one transmit
1228 command. If this feature is supported, the transmit CPBs can be linked in one transmit
1231 All UNDIs support fragmented frames, now all network devices or protocols do. If a fragmented
1232 frame CPB is given to UNDI and the network device does not support fragmented frames
1233 (see !PXE.Implementation flag), the UNDI will have to copy the fragments into a local buffer
1234 before transmitting.
