Capacity math on ring full is wrong: we are looking at num_sg but that might be optimistic because of indirect buffer use. The implementation also penalizes fast path with extra memory accesses for the benefit of ring full condition handling which is slow path. It's easy to query ring capacity so let's do just that. This change also makes it easier to move vnet header for tx around as follow-up patch does. Signed-off-by: NMichael S.
