Currently qdisc ingress handling (sch_handle_
set a return value and it is left to the old return value of
the caller (__netif_
the packet is consumed, caller will stop and return this value
as if the packet was dropped.
Also, include set of patches to increase stability with connection tracking offload, including reduced cpu load and possible deadlock on cleanup.
* What it could break.
Packet on egress tc rule forwarding to a ingress tc rule will drop.
High cpu load. Possible deadlock on cleanup.
* How to test
Run connection tracking hw offload scenario with millions of flows, check cpu load, test cleanup and readd scenarios.
summary: |
- Fix return value of qdisc ingress handling on success + Increase stability with connection tracking offload |
