Shannon Nelson 5b039241fe ionic: simplify TSO descriptor mapping ... One issue with the original TSO code was that it was working too hard to deal with skb layouts that were never going to show up, such as an skb->data that was longer than a single descriptor's length. The other issue was trying to arrange the fragment dma mapping at the same time as figuring out the descriptors needed. There was just too much going on at the same time. Now we do the dma mapping first, which sets up the buffers with skb->data in buf[0] and the remaining frags in buf[1..n-1]. Next we spread the bufs across the descriptors needed, where each descriptor gets up to mss number of bytes. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S.
