Thanks. I reworded the commit message as:
The intention is that, as each OpenFlow 1.1 and 1.2 feature is added to Open
vSwitch, the corresponding protocol definitions will be broken up this way:
- Definitions that are the same in OF1.0 and OF1.1 will retain the "OFP"
or "ofp" prefix and move to openflow-common.h.
- Definitions that are specific to OF1.0 will be renamed with an "OFP10"
or "ofp10" prefix and stay in openflow-1.0.h.
- Definitions that are specific to OF1.1 or to OF1.1 and OF1.2 will be
renamed with an "OFP11" or "ofp11" prefix and move to openflow-1.1.h.
- Definitions that are specific to OF1.2 will be renamed with an "OFP12"
or "ofp12" prefix and move to openflow-1.2.h.
