- * Many of the fields in CRB are status bits used by hardware
- * for implementation of the protocol. It's very dangerous to
- * mess around with the CRB registers.
- *
- * It's OK to read the CRB registers and try to make sense out of the
- * fields in CRB.
- *
- * Updating CRB requires all activities in Hub IIO to be quiesced.
- * otherwise, a write to CRB could corrupt other CRB entries.
- * CRBs are here only as a back door peek to hub IIO's status.
- * Quiescing implies  no dmas no PIOs
- * either directly from the cpu or from sn0net.
- * this is not something that can be done easily. So, AVOID updating
- * CRBs.
