SubjectRe: [PATCH v3] net: sysctl for RA default route MTU
From

> This patch introduces new ipv6 sysctl: ra_default_route_mtu.
> If it's set (> 0), it defines per-route MTU for any new default route

> This sysctl will help in the following configuration: we want to use

> should be set to ~9000 (statically or via RA).
>
> Due to dynamic nature of RA, setting MTU for default route will require
> userspace agent, that will monitor changes of default route
> and (re)configure it. Not simple. The suggested sysctl solves this
