Should each structure change be split into a separate patch?

This was discussed with Jingjing at

A raw flow provides a generic way for vendors to add their vendor
specific input flow. In our case, it is possible to match several flows
in a single rule. For example, it's possible to set an ethernet, vlan,
ip and tcp/udp flows all in a single rule. We can specify all of these
flows in a single raw input flow, which can then be passed to cxgbe flow
director to set the corresponding filter.
On similar lines, behavior_arg provides a generic way to pass extra
action arguments for matched flows. For example, in our case, to
perform NAT, the new src/dst ip and src/dst port addresses to be
re-written for a matched rule can be passed in behavior_arg.
Thanks,
Rahul
