By registering component related functions to the pointers,
we can easily manage them within a for-loop and simplify the
logic of clock control significantly.

Sorry I just noticed that; can you please remove the leading "_" from
all
of those?

_ethdr -> ethdr or mtk_ethdr
_merge -> merge or mtk_merge
_rdma  -> rdma  or mtk_rdma

Thanks,
Angelo


Sure. Will do in the next version.
The reason I didn't use mtk_* is simply because of the column width
will exceed 100 characaters.


Okay that would not be good, I guess that just `ethdr`, `merge`, `rdma` will
be fine then.

Cheers,
Angelo

Thanks,
Shawn
