When CAKE is deployed on a gateway that also performs NAT (which is a
common deployment mode), the host fairness mechanism cannot distinguish
internal hosts from each other, and so fails to work correctly.
To fix this, we add an optional NAT awareness mode, which will query the

At lower bandwidths, the transmission time of a single GSO segment can add
an unacceptable amount of latency due to HOL blocking. Furthermore, with a
software shaper, any tuning mechanism employed by the kernel to control the
maximum size of GSO segments is thrown off by the artificial limit on
ban
The ingress mode is meant to be enabled when CAKE runs downlink of the
actual bottleneck (such as on an IFB device). The mode changes the shaper
to also account dropped packets to the shaped rate, as these have already
traversed the bottleneck.
Enabling ingress mode will also tune the AQM to alway

This patch series adds the CAKE qdisc, and has been split up to ease
review.
I have attempted to split out each configurable feature into its own patch.
The first commit adds the base shaper and packet scheduler, while
subsequent commits add the optional features. The full userspace API and

This adds a callback to netfilter to extract a conntrack tuple from an skb
that works before the _nfct skb field has been initialised (e.g., in an
ingress qdisc). The tuple is copied to the caller to avoid issues with
reference counting.
The callback will return false when conntrack is not loaded,
This adds support for DiffServ-based priority queueing to CAKE. If the

limits that tier's rate to a fraction of the overall shaped rate, to
discourage trying to game the priority mechanism.
CAKE defaults to a simple, three-tier

The previous code was optimistic, accepting the offload of whole action
chain when there was a single known action (drop/redirect). This results
in offloading a rule which should not be offloaded, because its behavior
cannot be reproduced in the hardware.
For example:
$ tc filter add dev eno1 par

The new mini-CQE format includes the stride index, byte count and
packet checksum.
Stride index is needed for striding WQ feature.

Thanks for clarifying that first ip will be used as primary ip.
I have 2 further queries on this.
1. How can this survive across reboots without having a custom script
on boot up? Like some ifcfg file,etc.
2. is there a way to tell to make a given ip as primary, irrespective of order?

The RTL8366RB is an ASIC with five internal PHYs for
LAN0..LAN3 and WAN. The PHYs are spawn off the main
device so they can be handled in a distributed manner
by the Realtek PHY driver. All that is really needed
is the power save feature enablement and letting the
PHY driver core pick up the IRQ fr
This is a second RFC version of the DSA driver for Realtek
