[Cake] Does the latest cake support "tc filter"?

Hello developers, I've seen the mail in the netdev mailing list, saying "other tc filters supported". So can I use "tc filter" to attach specified traffic to a specified tin without DSCP marks? It's helpful when dealing with ingress traffic where iptables DSCP mark won't work. Thanks in advance.

[Cake] [PATCH net-next v12 2/7] sch_cake: Add ingress mode

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

[Cake] [PATCH net-next v12 1/7] sched: Add Common Applications Kept Enhanced (cake) qdisc

sch_cake targets the home router use case and is intended to squeeze the most bandwidth and latency out of even the slowest ISP links and routers, while presenting an API simple enough that even an ISP can configure it. Example of use on a cable ISP uplink: tc qdisc add dev eth0 cake bandwidth

[Cake] [PATCH net-next v12 4/7] sch_cake: Add NAT awareness to packet classifier

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 kernel conntrack

[Cake] [PATCH net-next v12 3/7] sch_cake: Add optional ACK filter

The ACK filter is an optional feature of CAKE which is designed to improve performance on links with very asymmetrical rate limits. On such links (which are unfortunately quite prevalent, especially for DSL and cable subscribers), the downstream throughput can be limited by the number of ACKs

[Cake] [PATCH net-next v12 6/7] sch_cake: Add overhead compensation support to the rate shaper

This commit adds configurable overhead compensation support to the rate shaper. With this feature, userspace can configure the actual bottleneck link overhead and encapsulation mode used, which will be used by the shaper to calculate the precise duration of each packet on the wire. This feature

[Cake] [PATCH net-next v12 7/7] sch_cake: Conditionally split GSO segments

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
