Subject: [PATCH 1/2] bridge: leave carrier on for empty bridge
Date: Fri, 02 Sep 2011 10:22:21 -0700	[thread overview]
Message-ID: <20110902172247.396753508@vyatta.com> (raw)
In-Reply-To: 20110902172220.830228928@vyatta.com

[-- Attachment #1: br-carrier-default.patch --]
[-- Type: text/plain, Size: 955 bytes --]

This resolves a regression seen by some users of bridging.
Some users use the bridge like a dummy device. 
They expect to be able to put an IPv6 address on the device
with no ports attached during boot.

Note: the bridge still will reflect the state of ports in the
bridge if there are any added.

This fix needs to go to stable for 3.0 and 2.6.39
