BPF programs of BPF_PROG_TYPE_CGROUP_SKB need to access headers in the

Not seeing where this is the case in the team driver today? They were actually
calling __netpoll_cleanup synchronously
rtl_rx() and rtl_tx() are called only if the respective bits are set
in the interrupt status register. Under high load NAPI may not be
able to process all data (work_done == budget) and it will schedule
subsequent calls to the poll callback.
rtl_ack_events() however resets the bits in the interrupt

The nfp driver is currently always JITing the BPF for 4 context/thread
mode of the NFP flow processors. Tell this to the disassembler,
otherwise some registers may be incorrectly decoded.

This patch proposes to extend the sk_lookup() BPF API to the
XDP hookpoint. The sk_lookup() helper supports a lookup
on incoming packet to find the corresponding socket that will
receive this packet. Current support for this BPF API is
at the tc hookpoint. This patch will extend this API at XDP

Having a separate "slow event" handler isn't needed because all
interrupt events trigger asynchronous activity. And in case of SYSErr
we have bigger problems than performance anyway.
This patch also allows to get rid of acking interrupt events in the
NAPI poll callback.

This series contains documentation fixes and updates for Intel wired LAN
drivers.
The following was done:
- Updated incorrect URLs
- removed document references which did not apply to the current
in-kernel drivers
- added documentation for fm10k driver
- added missing documentation on exist
Before making the conversion to the RST (reStructured Text) format, there
are changes needed to the documentation so that there are no build errors.
Also fixed old/broken URLs to the correct or updated URL.
