What is this series doing? Where is your "0/4" cover letter which would tell us this? Also: > OVS compilation breaks here after this patchset since flow_stats > structure is already defined in include/net/flow_offload.h. This patch > is new in this batch. You need to explain in more detail and in more context what this means. Does the build break when this patch is applies? If so, why is that OK? I'm tossing this series until you submit it properly.
