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.

This patch has been applied against commit 29a720c1042f ("Merge branch
'Marvell-mvpp2-improvements'")

Thanks: Magnus
