Indeed I was thinking doing a change in .ini files related rte flow in 17.11

rte_flow is a method to implement some filtering features, rte_flow
itself is not a device feature. And filtering features already listed in
.ini file.

So I was thinking removing rte_flow from feature table, and update
existing filter features as something like:
"Ethertype filter = L"  --> Feature exist and implemented using Legacy
method.
"Ethertype filter = Y"  --> Feature exist and implemented using rte flow

Does it make sense?
