Due to performance, uadk tries to leave many configuration options to users. This gives users great flexibility, but it also leads to a problem that the current initialization interface has high complexity. Therefore, in order to facilitate users to adapt quickly, a new set of interfaces is provided.
The 'wd_alg_init2_()' will complete all initialization steps. There are 4 parameters to describe the user configuration requirements. @alg: The algorithm users want to use. @sched_type: The scheduling type users want to use. @task_sp: Reserved.
task_type ？ 同步或者异步吗，建议说明下。
给龙芳的切软算预留的接口，当前代码用不上，为了避免后续修改接口，所以这里提前加上， 在后续特性使能的时候会加上描述。
@ctx_params: The ctxs resources users want to use. Include per operation type ctx numbers and business process run numa.
If users think 'wd_alg_init2_()' is too complex, wd_alg_init2() is a simplified packaging and will use the default value of numa_bitmask and ctx_nums.

建议跟前一个参数sched_type命名一致，用task_type。
但是，如果是表示切换开关使能。 建议用fall_back更合适。task_type容易跟同步，异步混淆。
fall_back; /* 是否切换，0：表示不降级切换。 1：表示算力资源耗尽，搜索切换下一级算力*/
这个参数不是切换软算这种标志，它的定义如下： enum alg_task_type { TASK_SOFT = 0x0, TASK_HW, TASK_MIX };
表示的是业务类型，算法方式，硬算方式和混合模式,只有混合模式有切软算， 这种情况下fall_back定义不符合语义。
我感觉有点复杂且过设计了。 1、这个需要用户去指定设置哪种类型，用户怎么知道他是用软算还是硬算。 2、用户大部分是不感知用哪种算力的。唯一有可能感知的是用硬件提升下安全性。
所以，再来看下原始需求是：是用单一算力，还是用更大带宽算力。
用fall_back如果感觉命名不好，可以换一种命名。 但是它想实现的需求是： fall_back==0：表示只用固定一种算力，比如硬件快且安全，那就固定选最高优先级的硬件，不能切软算。 fall_back==1；表示用统一大算力，这个时候应用不管用啥算力，只要能给他拼起更多算力就行，最高优先级用完， 降级用次优先级算力。所以可能有硬算1+硬算2组合；硬算1+软算1组合. 这样适用性会更广。
上面那个原始需求的描述不够完整，当前我们的UADK已经不强调一定需要硬算才可以使用，单独使用软算的场景也是存在的。 因此，直接使用0,1表示是否用软算进行补充的情况只是 默认使用硬算的情况，对于单独使用软算就无法支持了.
纯软算就是使用过程中只用软算，至于扩展，只在软算层面扩展下去软算1 + 软算2 + ... 纯硬算就是使用过程中只用硬算，至于扩展，只在硬算层面扩展下去硬算1 + 硬算2 + ... 混合计算就是使用过程中都可以用，至于扩展就是按照优先级，不管软算和硬算，只有当前可以执行业务的，直接按照优先级使用就行
这种方式就只从业务层面进行考虑，不需要考虑内部实现细节。
