codel & fq_codel packet schedulers are now able to have a threshold for CE marking packets, regardless of the drop/nodrop decision taken by CoDel. This is particularly useful for dctcp and variants, that do not use traditional ECN. Note that fq_codel users would have to specify noecn if ce_threshold is used, otherwise results would be not very interesting, as ecn is default on for fq_codel. $ tc -s qdisc show dev eth1 qdisc codel 8002: root refcnt 45 limit 1000p target 5.0ms ce_threshold 1.0ms interval 100.0ms Sent 4908469888317 bytes 3351813967 pkt (dropped 0, overlimits 0 requeues 21624365) rate 37671Mbit 3231836pps backlog 4904740b 250p requeues 21624365 count 0 lastcount 0 ldelay 1.1ms drop_next 0us maxpacket 68130 ecn_mark 0 drop_overlimit 0 ce_mark 410861803 Signed-off-by: Eric Dumazet <edumazet@google.com> |

How to compile this.
--------------------
1. libdbm
arpd needs to have the db4 development libraries. For Debian
users this is the package with a name like libdb4.x-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a Config file which
contains whether or not ATM is available, etc.
3. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
