H A Ddefconfigace36475 Sun Jul 11 23:21:15 CDT 2021 Joel Stanley <joel@jms.id.au> linux-aspeed: Disable IPV6 SIT device

No one is using this device on OpenBMC systems, and there is no
code to manage it in phosphor-networkd as of March 2021:

> [...] if you don't add IPv6 addresses to the sit interface
> it doesn't do anything. The defacto way to do that on an interface in
> OpenBMC is to have it managed by phosphor-networkd. On top of this, to
> support sit you would need a way to configure the local / remote IPv4
> addresses used to back it. You can configure the linux kernel to build
> sit functionality but not create sit devices by default (I don't know
> how they haven't changed this yet in default kconfigs...) and it will
> still let you make them on the fly.

Facebook and Google systems force this option off already:
