Subject: [Cake] How to use the cake ack-filter?
Date: Wed, 20 Dec 2017 23:23:16 +0100	[thread overview]

Hi all,

Support for the ack-filter was added to LEDE with this commit:
https://github.com/lede-project/source/commit/0589979f7ba1483c4d7c83a63d74c85d2a6e4bb2
Since I have an asymmetrical internet connection (10/1) I want to test
this feature. However, how to enable it?
With some deducing, I have added ack-filter to the following lines in
/etc/config/sqm:
       option iqdisc_opts 'nat dual-dsthost ack-filter'
       option eqdisc_opts 'nat dual-srchost ack-filter'

With these lines, if I issue  tc -d qdisc I get the following output
which I think shows that the ack-filter is enabled:
qdisc noqueue 0: dev lo root refcnt 2
qdisc fq_codel 0: dev eth0 root refcnt 2 limit 10240p flows 1024

besteffort dual-dsthost nat wash ack-filter rtt 100.0ms raw
total_overhead 14 hard_header_len 14

Have I deduced correctly how to enable the ack-filter?

Kinds regards,
Bart
