/* a packet structure for receiving SMB messages; locked by smb_globalLock.
 * Most of the work involved is in handling chained requests and responses.
 *
 * When handling input, inWctp points to the current request's wct field (and
 * the other parameters and request data can be found from this field).  The
 * opcode, unfortunately, isn't available there, so is instead copied to the
 * packet's inCom field.  It is initially set to com, but each chained
 * operation sets it, also.
 * The function smb_AdvanceInput advances an input packet to the next request
 * in the chain.  The inCom field is set to 0xFF when there are no more
 * requests.  The inCount field is 0 if this is the first request, and
 * otherwise counts which request it is.
 *
 * When handling output, we also have to chain all of the responses together.
 * The function smb_GetResponsePacket will setup outWctp to point to the right
 * place.
