Int 7C Fn 0006  - Sk-upps Data Link Interface API - Transmit Frame         [N]

   AX = 0006h
   ES:BX -> Mbuf (see AX=0004h)

Return: nothing

Notes: The DLI will send LENGTH bytes found in the Mbuf's DATA area starting
     at OFFSET. A complete and valid frame must be stored there. The DLI
     will only copy the current node address (see AX=0003h) to the
     source node field of the frame's MAC header.
   On Ethernet, the DLI will always send a minimum of 60 bytes, regardless
     of the value found in the LENGTH field.
   This function returns immediately; the DLI will call the protocol's
     Transmit Upcall (see AX=0007h) when the frame has been sent.
   The Mbuf's IN USE field will be non-zero until the DLI calls the
     Transmit Upcall.

Transmit Upcall called with:
   ES:BX -> Mbuf (NEXT field destroyed)
   interrupts disabled

Note:  On FDDI the bytes of the source and destination node fields in the MAC
     header have been bit-swapped to physical address format.
