net: mvpp2: cls: Use a bitfield to represent the flow_type
As of today, the classification code is used only for RSS. We split the
incoming traffic into multiple flows, that correspond to the ethtool
flow_type parameter.
We don't want to use the ethtool flow definitions such as TCP_V4_FLOW,
for several reason :
- We want to decorrelate the driver code from ethtool as much as
possible, so that we can easily use other interfaces such as tc flower,
- We want the flow_type to be a bitfield, so that we can match flows
embedded into each other, such as TCP4 which is a subset of IP4.
This commit does the conversion to the newer type.
