This small series improves AF_XDP performance for the i40e NIC. The first patch optimizes the Tx completion path for AF_XDP and the second one removes a division in the data path for the normal SKB path, XDP as well as AF_XDP. Overall, the throughput of the l2fwd application in xpdsock improves with around 4% on my machine.
