This patch series introduces basic XDP support for fbnic. To enable this,
it also includes preparatory changes such as making the HDS threshold
configurable via ethtool, updating headroom for fbnic, tracking
frag state in shinfo, and prefetching the first cacheline of data.

Changelog:
V2:
* P1: Enforce a lower bound on header bytes and start splitting all
frames on L2, L3, or L4 header boundaries based on frame size when
hds_thresh is below this threshold
* P5:
- Update commit message
- Update fbnic_run_xdp() to add comment about multi-frag check
* P8: Address warnings with htmldocs
