OK, makes sense. One other possibility would be to disable TSO if CMA_SIZE_MBYTES is set to a too small value (i.e. its default). But I don't think this would be a good solution either. The drawback is the default configuration when selecting DMA_CMA won't work for PPv2. Anyway, I'll send a v2 without these patches. Thanks!
