The tc modify flow put always delete the original flow first and then add the new flow. If the modfiy flow put operation failed, the flow put operation will change from modify to create if success to delete the original flow in tc (which will be always failed with ENOENT, the flow is already be deleted before add the new flow in tc). Finally, the modify flow put will failed to add in kernel datapath.
