Description

If "bond01" is an alias interface of "bond0" created for example like this:

ip addr add 1.2.13.6/24 brd + dev bond0 label bond01

then the following sequence of commands results in an error when adding NI on bond0:

# modprobe lnet
# lnetctl lnet configure
# lnetctl net add --net tcp --if bond01
# lnetctl net add --net tcp --if bond0
---
add:
- net: 
  errno: -17
  descr: Object exists
...

Adding bond0 first, then bond01 works fine.
