[gentoo-user] docker and CONFIG_IPVLAN

[gentoo-user] docker and CONFIG_IPVLAN

Hello,

I am getting this warning when updating app-emulation/docker:

 CONFIG_IPVLAN:         is not set when it should be.

But in the linux kernel configuration I cannot find IPVLAN at:
-> Device Drivers

 -> Network device support
   -> Network core driver support

I am using gentoo-sources. But the same thing happens with vanilla-sources
(versions 4.8.4)

Does anybody knows why?

Symbol: IPVLAN [=m]
Type : tristate
Prompt: IP-VLAN support
Location:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
-> Network core driver support (NET_CORE [=y])
Defined at drivers/net/Kconfig:149
Depends on: NETDEVICES [=y] && NET_CORE [=y] && INET [=y] && IPV6 [=y]

Do you have NETDEVICES, NET_CORE, INET, and IPV6 all enabled?  If not,
you can't enable IPVLAN.

​Thank you for the answer Rich, it must be IPV6!

I vaguely recall running into something like that myself.  Some of
these dependencies are not at all obvious.  In general the make
menuconfig (or especially xconfig) search options will quickly find an
item even if it is hidden in the menu, and show you which flags aren't
set in your context.  Granted, that often leads to another search, and
possibly finding other items not enabled.  It rarely goes deeper than
2-3 levels though.

In "make menuconfig" simply type slash and your search string:

> /IPVLAN

It should show you where to look and what are the depends to make it
visible.
