Subject: [PATCH] ip6: ignore cached/cloned route notifications from the
|
| 5 |
kernel (lp:1038541) (bgo #671767)
|
| 6 |
|
| 7 |
The kernel periodically adds routes for specific operations, including
|
| 8 |
when pinging any host. These are temporary routes and aren't part of
|
| 9 |
the interface's permanent routing configuration, so we should ignore
|
| 10 |
them.
