Subject: [PATCH net-next v3 00/12] bnxt_en: Add XDP support.

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.

v3: Removed Kconfig option.
    Pass modified offset and length to stack for XDP_PASS.
    Improved buffer recycling scheme for XDP_TX.
    Other minor fixes.

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.
