Cover letter [PATCH net-next v4 0/5] 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()
Paolo Abeni (5):
ipv6: add fib6_has_custom_rules() helper
ipv6: keep track of routes using src
ipv6: introduce and uses route look hints for list input.
