- * information.
- *
- * 1. The address of the actual message data buffer in user (host) memory.
- * 2. The length of that message buffer.
- * 3. The status information for that particular buffer. The eight most
- * significant bits of md1 are collectively termed the STATUS of the
- * descriptor.
- *
- * Descriptor md0 contains LADR 0-15, the low order 16 bits of the 24-bit
- * address of the actual data buffer. Bits 0-7 of descriptor md1 contain
- * HADR, the high order 8-bits of the 24-bit data buffer address. Bits 8-15
- * of md1 contain the status flags of the buffer. Descriptor md2 contains the
- * buffer byte count in bits 0-11 as a two's complement number and must have
- * 1's written to bits 12-15. For the receive entry md3 has the Message Byte
- * Count in bits 0-11, this is the length of the received message and is valid
- * only when ERR is cleared and ENP is set. For the transmit entry it contains
- * more status information.
