I'd say in both. Please open 2 bug reports.

YaST2 does not allow to configure it per-interface [bug or missed 
feature], wicked does not consider settings in ifsysctl files [bug].

No, it isn't. It is just autoconfigured.

> Witch command Is for deactivate iPv6 for a NIC

See https://www.kernel.org/doc/Documentation/networking/ip-sysctl.txt

echo "net.ipv6.conf.foo0.disable_ipv6 = 1" > 
/etc/sysconfig/network/ifsysctl-foo0

or

echo "net.ipv6.conf.foo0.disable_ipv6 = 1" > /etc/sysconfig/network/ifsysctl

You can also disable the address-:
    net.ipv6.conf.foo0.autoconf = 0
and/or route autoconfiguration:
    net.ipv6.conf.foo0.accept_ra = 0.

When you want to disable it globally, you may add an "all" policy to:

/etc/sysctl.d/99-sysctl.conf
net.ipv6.conf.all.disable_ipv6 = 1


> Witch command is for correct route for IPv6

The routes are AFAIS correct. IPv6 routes usually do not go via a router
from same prefix, but via link-local (fe80:...) addresses of the router.

Yes, going to fix it. "man ifsysctl" on SLE-11.

> This is a Strong change for network ?

IMO no changes at all. Most things are same as on SLES-11 at this place.

=> yast2 lan
