58  * A GSI channel is a unidirectional means of transferring data to or
59  * from (and through) the IPA.  A GSI channel has a ring buffer made
70  * The input to a GSI channel is a FIFO of type/length/value (TLV)

93  * @pad_align:	power-of-2 boundary to which packet payload is aligned
94  * @aggr_close_eof: whether aggregation closes on end-of-frame
