Sharing the same physical interface among multiple bond interfaces causes information to be lost within the error message
Reproduce
set interfaces bonding bond10 member interface eth1 set interfaces bonding bond10 member interface eth2 set interfaces bonding bond20 member interface eth1 set interfaces bonding bond20 member interface eth2 commit
[ interfaces bonding bond10 ] Can not add interface "eth1" to bond, it is already a member of bond "b"! [[interfaces bonding bond10]] failed [ interfaces bonding bond20 ] Can not add interface "eth1" to bond, it is already a member of bond "b"!
It should infact output the full name of the bond interface
