Hi,

does anyone know what happened to the 'Ingress Qdisc' kernel option
mentioned on [1], and what the replacement would be?

I'm trying to follow [2] to set up some simple traffic shaping with the
intention to improve VOIP quality.

I'm using 4.1.12-gentoo and it contains Ingress Qdisc.  Look for 
NET_SCH_INGRESS:

grep -i SCH_INGRESS /usr/src/linux/.config
# CONFIG_NET_SCH_INGRESS is not set

heimdali ~ # grep NET_SCH_INGRESS /usr/src/linux/.config
heimdali ~ # uname -a
Linux heimdali 4.0.5-gentoo #8 SMP Sun Sep 27 22:52:33 CEST 2015 x86_64 Intel(R) Xeon(R) CPU X5675 @ 3.07GHz GenuineIntel GNU/Linux


So I don't have that at all.  Isn't that weird?  I used qdiscs years
ago, and it would seem very unlikely that the feature was removed for
this kernel version, or for some kernel versions, and then brought back
with 4.1.12.  I thought it might have been replaced with something else,
yet apparently it hasn't.

Grepping .config proves nothing. If a requirement of the option is not
set, the option may not appear in .config. The only reliable test is the
search facility in make *config.

Search facility?

I only use menuconfig and often times, it's difficult to find a
particular option I'm looking for.

Like the wiki page tells you where to look, so I look there, and the
option isn't there while others shown on the wiki page are --- very
likely using a different kernel version.  Now where is the option I need
to enable?  A tedious search begins ...

Is there a good way to find where options are?

in make menuconfig, type "/" then a search string. Just like less.

Then start hunting.

Touch the / key, then enter the option name minus the CONFIG_ prefix. Case 
is not sensitive.

I forgot to add that if more than one result is returned, they're numbered. 
Then if you hit the number key of the one you want, you go straight to it.

Just a quick side note, because it doesn't seem that many people know about
it: you can use "make nconfig" instead of "make menuconfig".
It's another ncurses based interface, similar to menuconfig but different
enough to prefer one or the other.
Keep in mind that you can access the menu items with both the F1-F9 keys
and the 1-9 keys.

And when you exit from reading that selection you get back to the
results list.

It's pretty slick and sure beats looking where I "think" it should be or
grepping KConfig files.

Wow, that might save me a lot of time :)

And qdisc is extremely well hidden, I'd never have found that.  It
doesn't show up unless other options are enabled:  You have to know
exactly what you want to enable before even knowing that it's there.

How are we supposed to be able to configure a kernel when we can't even
see the available options anymore?

By using a tool that *does* show you the options and how to make them
available.

The kernel devs have no desire to hold anyone's hand; they assume
(correctly IMNSHO) that anyone configuring a kernel knows what they are
doing and knows the tools to use. With that approach, sometimes the user
runs into things they can't find, and it's an acceptable price to pay.

Which tool is that?

Assuming that when someone wants to do something they already know what
they are doing and not allowing them to learn by hiding what there is to
know leads to nobody being able to do anything.

Ask around: How many people do know exactly what they are doing when
they are configuring a kernel?  You only need to find one who doesn't to
prove the supposed assumption of the kernel developers wrong.  And I
never really knew what I was doing when I configured a kernel.  Do you?
Who does?

By using the search tool. without it, all the options would show up all
the time, even those you don't want and can't enable. Hiding all
irrelevant options makes kernel configuration almost sane to manage.

It is also worth mentioning xconfig and gconfig for a GUI-fied front end, 
which also offer search options.
