If turbo equalization is to be performed.
If set, saturate soft output to +/-127
Set to 1 to start iteration from even, else odd; one iteration = max_iteration + 0.5

Set if soft output is required to be output

Set to enable early termination mode
Set if a device supports decoder dequeue interrupts
Set if positive LLR encoded input is supported. Positive LLR value represents the level of confidence for bit '1', and vice versa for bit '0'. This is mutually exclusive with RTE_BBDEV_TURBO_NEG_LLR_1_BIT_IN when used to formalize the input data format.
Set if negative LLR encoded input is supported. Negative LLR value represents the level of confidence for bit '1', and vice versa for bit '0'. This is mutually exclusive with RTE_BBDEV_TURBO_POS_LLR_1_BIT_IN when used to formalize the input data format.
Set if positive LLR soft output is supported. Positive LLR value represents the level of confidence for bit '1', and vice versa for bit '0'. This is mutually exclusive with RTE_BBDEV_TURBO_NEG_LLR_1_BIT_SOFT_OUT when used to formalize the input data format.
Set if negative LLR soft output is supported. Negative LLR value represents the level of confidence for bit '1', and vice versa for bit '0'. This is mutually exclusive with RTE_BBDEV_TURBO_POS_LLR_1_BIT_SOFT_OUT when used to formalize the input data format.
Set if driver supports flexible parallel MAP engine decoding. If not supported, num_maps (number of MAP engines) argument is unusable.
Set if a device supports scatter-gather functionality
Set to keep CRC24B bits appended while decoding. Only usable when decoding Transport Block mode.
Set to drop CRC24B bits not to be appended while decoding.
