XDP for idpf is currently 5 chapters: * convert Rx to libeth; * convert Tx completion to libeth (this); * generic XDP and XSk code changes; * actual XDP for idpf via libeth_xdp; * XSk for idpf (^).
Part II does the following: * adds generic libeth Tx completion routines; * converts idpf to use generic libeth Tx comp routines; * fixes Tx queue timeouts and robustifies Tx completion in general; * fixes Tx event/descriptor flushes (writebacks). Most idpf patches again remove more lines than adds. Generic Tx completion helpers and structs are needed as libeth_xdp (Ch. III) makes use of them. WB_ON_ITR is needed since XDPSQs don't want to work without it at all. Tx queue timeouts fixes are needed since without them, it's way easier to catch a Tx timeout event when WB_ON_ITR is enabled.

It's not generic, uses old Ethtool interfaces and is written using macro templates which made it barely readable (Kuba).
