UNDI_APIEntry_old (

/*++
Routine Description:
This is the main SW UNDI API entry using the older nii protocol.
The parameter passed in is a 64 bit flat model virtual
address of the cdb. We then jump into the common routine for both old and
new nii protocol entries.
Arguments:
CdbPtr - Pointer to the command descriptor block.
AdapterInfo - Pointer to the NIC data structure information which the UNDI driver is layering on..
Returns:
None

// Instead of using the global buffer whose address is allocated within the

// why!!!
// if our address is > 4GB, the map call creates another buffer below 2GB and

// map time or unmap time depending on the map direction.
// UNDI will not complain since we already mapped the buffer to be
// within the 2GB limit but will not use (I know undi) the mapped address
// since it does not give the user buffers to the NIC's receive unit,
// It just copies the received packet into the user buffer using the virtual
// (CPU) address rather than the mapped (device or physical) address.
// When the UNDI call returns, if we then unmap the buffer, we will lose
// the contents because unmap copies the contents of the mapped buffer into
// the original buffer (since the direction is FROM_DEVICE) !!!
//
// this is not a problem in Undi 3.1 because this undi uses it's map callback
