This piece of Debian documentation states that package
ifenslave is necessary for bonding:
First install the ifenslave package, necessary to enable bonding
Yet I know of two Debian 7.10 (wheezy) hosts where
dpkg --get-selections | grep ifenslave returns
ifenslave-2.6 install (i.e. package is not installed) and there are multiple entries
MII Status: up.
So is package
ifenslave really necessary for bonding or is it not?
