Re: [PATCH bpf-next v2 00/14] Introduce AF_XDP buffer allocation API

Overview

Driver adoption for AF_XDP has been slow. The amount of code required
to proper support AF_XDP is substantial and the driver/core APIs are
vague or even non-existing. Drivers have to manually adjust data
offsets, updating AF_XDP handles differently for different modes
(aligned/unaligned).

This series attempts to improve the situation by introducing an AF_XDP
buffer allocation API. The implementation is based on a single core
(single producer/consumer) buffer pool for the AF_XDP UMEM.

I'll need to respin, adapting to Jesper's 'xdp-grow-tail' merge.
