Hi Zhichao,

Actually, I think it is better to describe a functional impact in commit message.
It could make it easier to understand the issue.

It could be:
Revert this part to disable mark action in switch and recover the mark action hit in FDIR
by default. For current impl, switch filter missed the consumption part of mark id for app.
And switch filter capture the rules first rather than FDIR which makes FDIR rules lost. 

Does it sound OK to you?
