Package: bridge-utils
Version: 1.5-13
Severity: important
When we have first set up a vlan like for example eth0.2000 the bridge setup
will later fail to create vlans that are substrings of the already created
vlans, like eth0.2.
This is caused by the greps we are doing on /proc/net/dev not being
delimited.
Here is the proposed patch for stable:
