Detailed Description

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

In CB-mode, CRC24A/B is an optional operation. K size parameter is not affected by CRC24A/B inclusion, this only affects the inbound mbuf data length. Not all BBDEV PMDs are capable of CRC24A/B calculation. Flags RTE_BBDEV_TURBO_CRC_24A_ATTACH and RTE_BBDEV_TURBO_CRC_24B_ATTACH informs the application with relevant capability. These flags can be set in the op_flags parameter to indicate BBDEV to calculate and append CRC24A to CB before going forward with Turbo encoding.

In TB-mode, CRC24A is assumed to be pre-calculated and appended to the inbound TB mbuf data buffer.

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