Subject: [PATCH] IPaddr2: add option for specifying IPv6's preferred_lft
|
|
|
79554c |
|
|
|
79554c |
This change allows setting the preferred_lft option when creating an
|
|
|
79554c |
IPv6 address. This can be used to ensure that the created IP address
|
|
|
79554c |
will not be used as a source address for routing.
