Add error bit used to report TFC (NH=59) packets. Such events MUST be
generated in SYNC and ASYNC modes. In INLINE mode generation of this
error is controlled by inline_tfc_packets_drop config field. Support for
dropping or delivering TFC packets in INLINE mode is reported to
application via inline_tfc_packets_drop and inline_tfc_packets_deliver
capabilities.
