I have patched support for the v11 into trunk but would need some testers since I do not have the hardware myself.
Images (both 15.05.1 and trunk) can be found here.
I had reports of the TP-Link web interface refusing the image so please try flashing to TFTP and report back to me. There might be a firmware lock in place in the TP-Link web interface.
If the site does not resolve, please try another DNS provider like OpenDNS or Google's DNS servers.
Everyone is of course welcome to test but you need to be able to fall back to TFTP if things go wrong.
Your feedback is welcome!
Edit: since v11 support has been upstreamed, I am now only providing a 15.05.1 image. You can pull the trunk build from OpenWrt's official snapshots.
