commit 028524317d8d0011ed38e86e507a06738a5b5a97 from upstream
|
|
|
|
IPv6 routes need the device argument for link-local routes, or they
|
|
cannot be used at all. E.g. "gateway fe80::def" seems to be used in
|
|
some places, but kernel refuses to insert the route unless device
|
|
name is explicitly specified in the route addition.
