Paolo Abeni says: ==================== net: introduce and use route hint This series leverages the listification infrastructure to avoid unnecessary route lookup on ingress packets. In absence of custom rules, packets with equal daddr will usually land on the same dst. When processing packet bursts (lists) we can easily reference the previous dst entry. When we hit the 'same destination' condition we can avoid the route lookup, coping the already available dst. Detailed performance numbers are available in the individual commit messages. v3 -> v4: - move helpers to their own patches (Eric D.) - enable hints for SUBTREE builds (David A.) - re-enable hints for ipv4 forward (David A.) v2 -> v3: - use fib*_has_custom_rules() helpers (David A.) - add ip*_extract_route_hint() helper (Edward C.) - use prev skb as hint instead of copying data (Willem ) v1 -> v2: - fix build issue with !CONFIG_IP*_MULTIPLE_TABLES - fix potential race in ip6_list_rcv_finish() ==================== Acked-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
