   4 Subject: [PATCH] bridge: leave carrier on for empty bridge
   5
   6 This resolves a regression seen by some users of bridging.
   7 Some users use the bridge like a dummy device.
   8 They expect to be able to put an IPv6 address on the device
   9 with no ports attached. Although there are better ways of doing
  10 this, there is no reason to not allow it.
  11
  12 Note: the bridge still will reflect the state of ports in the
  13 bridge if there are any added.
