Package: ifenslave
Version: 2.12
Severity: important
Dear Maintainer,
Bonding on Debian 11 Bullseye is not working, when using "bond-slaves int1
int2" syntax on the bonding interface.
However it seems to work, when defining bonding the other way around using
"bond-master bond1" on the interfaces which make up the bonding interface.
I came across bug #968368 and modified the ifenslave pre-up.d script, hence the
changes below.
The same config (using bond-slaves) was working fine in Debian Buster. In
Bullseye the bond interface stays DOWN and /proc/net/bonding/bond* also shows
mii-status down.
