Subject: [PATCH] Revert "wait for IPv6 RA if using none/static IPv6
|
|
|
e83cdd |
assignment"
|
|

This reverts commit c603419030136570b5944dc4620f62d07b9e82bb.
|

|
|
|

wait_for_ipv6_dad_link is only called from dhclient script,
|
|
|
e83cdd |
so the original intent "wait for IPv6 RA if using none/static IPv6 assignment"
|
|
|
e83cdd |
does not seem to be correct.
|
|
|
e83cdd |
|
|
|

Anyway, this brings an issue on isolated networks, where you don't
|
|
|
e83cdd |
have any routes outside. dhclient-script hangs on this check
|
|
|
e83cdd |
and after it times out, dhclient is able to set the address normally.
