Hi, Ferruh
This patch is the same as the following patch:

It was delegated to you.😂

> When supported RSS offload flow types are printed via 'show port info #'
> command, flow names are get from flow type array which is wrong and
> causing some RSS flow types not being displayed.

> Instead RSS flow type array should be used. Also helper functions added
> and existing code updated to use helpers.
