network interface bonding fails

[Stefan Lapers]

Binary package hint: ifenslave-2.6

When creating the following configuration on 10.10 ( as specified in https://help.ubuntu.com/community/UbuntuBonding#Ubuntu%2010.04%20and%20newer ) the device fails to come up, bringing it up requires a manual enslave commands.

The configuration below on 10.04, however it seems to break in 10.10

auto bond0
iface bond0 inet static
    bond-slaves eth3 eth5
    bond-mode 2
    bond-miimon 100
    address 192.168.1.1
    netmask 255.255.255.0

~# ifup bond0
SIOCSIFADDR: No such device
bond0: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
bond0: ERROR while getting interface flags: No such device
Failed to bring up bond0.

When inspecting /etc/network/if-pre-up.d/ifenslave it seems the bonding functionality is missing.
Also the dpkg package ifenslave-2.6 states that /etc/network/if-up.d/ifenslave is contained in the package, however it doesn't exist on the filesystem.
