Yong Wu June 16, 2021, 11:43 a.m. UTC
To improve the performance, We add some initial setting for smi larbs.
there are two part:
1), Each port has the special ostd(outstanding) value in each larb.
2), Two general setting for each larb.

In some SoC, this setting maybe changed dynamically for some special case
like 4K, and this initial setting is enough in mt8195.
