The first 10 patches refactor the code (rx/tx code paths and ring logic)
and add the basic infrastructure to support XDP. The 11th patch adds
basic ndo_xdp to support XDP_DROP and XDP_PASS only. The 12th patch
completes the series with XDP_TX.
Thanks to Andy Gospodarek for testing and uncovering some bugs.
v2: Addressed review comments from Alexei Starovoitov, Jakub Kicinski,
and David Miller:
- Added missing dma syncs.
- Added XDP headroom support.
- Added tracing in exception path.
- Clarified a parameter change.
