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

// IMPORTANT NOTE:
// In case of the older 3.0 UNDI, if the input buffer address is beyond 4GB,
// DO NOT call the map function on the given buffer, instead use
// a global buffer. The reason is that UNDI3.0 has some unnecessary check of
// making sure that all the addresses (whether or not they will be given
// to the NIC ) supplied to it are below 4GB. It may or may not use
// the mapped address after all (like in case of CPB and DB)!
// Instead of using the global buffer whose address is allocated within the
// 2GB limit if I start mapping the given buffer we lose the data, here is
// why!!!
// if our address is > 4GB, the map call creates another buffer below 2GB and
// copies data to/from the original buffer to the mapped buffer either at
// 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
// routine to map a cpu address to device address and it does it only if
// it is giving the address to the device and unmaps it before using the cpu
// address!
