When a VIF/VLAN interface is placed in admin down state but the lower
interface, serving the vlan, is moved from admin down -> admin up, all its
vlan interfaces will be placed in admin up state, too.
This is bad as a VLAN interface will become admin up even if its specified as
admin down after a reboot.
To reproduce:
set interfaces ethernet eth1 vif 20 disable
set interfaces ethernet eth1 disable
commit
delete interfaces ethernet eth1 disable
commit
Now check the interface state and it returns UP,LOWER_UP
7: eth1.20@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether 00:50:56:b3:09:07 brd ff:ff:ff:ff:ff:ff
inet6 fe80::250:56ff:feb3:907/64 scope link

Better implementation to assign link local addresses automatically because address only assigned to interfaces which supports IPv6 addresses.
|
|
Tunnel interfaces hot having any IPv6 Link Local address because Linux Kernel does not assign address due to missing MAC. I have implemented a function to generate a linl local address and assign it to the interface. Link local address is required for OSPF and other protocols.

Instead of using an Adapter pattern to make interfaces VLAN-aware, create a
derived class named VLANIf to represent a VLAN. This change was necessary to
eliminate mixed code in Interfaces class which was VLAN - free, but recently
gained some VLAN specific code for set_admin_state().
In addition this "autoresolves" the issue in T2894 as a bond vlan interface
will no longer change the lower interface.

All interface classes register themselves so that we can figure
out from an interface name what class is responsible for its
creation. In the case of Tunnel, it is not the case as multiple
different interfaces are sharing the same "tun" prefix.
Still many operations are the same and it should be done.

The Interface get_state/set_state were not clear about
if they edited the admin or operational state.
functions are now using admin_state and oper_state
for clarity.
