We're still seeing the same issue on Ubuntu Trusty running the linux- image-3.19.0-30-generic kernel.
Looking at this thread[0] on the Docker site which is referenced to in the kernel bugzilla for this issue, there is a reference[1] to a patch[2] on the netdev mailing list from 2015-11-05 by Francesco Ruggeri, later that day David Miller accepted it and queued it for -stable. The patch is currently in the master branch of Linus's tree, but hasn't made it into the 4.2 branch yet. The patch doesn't apply cleanly to the Canonical 3.19 branch, but it looks like it is mostly line skew. I haven't tried hacking it in yet.
