> Use libeth XDP infra to support running XDP program on Rx polling.
> This includes all of the possible verdicts/actions.
> XDP Tx queues are cleaned only in "lazy" mode when there are less than
> 1/4 free descriptors left on the ring. libeth helper macros to define driver-
> specific XDP functions make sure the compiler could uninline them when

> Use __LIBETH_WORD_ACCESS to parse descriptors more efficiently when
> applicable. It really gives some good boosts and code size reduction on
> x86_64:

> XDP only: add/remove: 0/0 grow/shrink: 3/3 up/down: 5/-59 (-54) with XSk:
> add/remove: 0/0 grow/shrink: 5/6 up/down: 23/-124 (-101)

> with the most demanding workloads like XSk xmit differing in up to 5-8%.
