Detailed Description

Operation structure for LDPC encode. An operation can be performed on one CB at a time "CB-mode". An operation can be performed on one or multiple CBs that logically belong to a TB "TB-mode".

The input data is the CB or TB input to the decoder.

The output data is the ratematched CB or TB data, or the output after bit-selection if RTE_BBDEV_LDPC_INTERLEAVER_BYPASS is set.

The output mbuf data structure is expected to be allocated by the application with enough room for the output data.
