xen-netback changes in #767261 break Mini-OS netfront

Hi,
after updating linux-image-3.16.0-4-amd64 from 3.16.7-2 to the latest
3.16.7-ckt2-1 networking on my rumprun-xen [1] domUs stopped working.
Here is an excerpt of the failure during Mini-OS boot:
net TX ring size 256
net RX ring size 256
netfront: node=device/vif/0 backend=/local/domain/0/backend/vif/21/0
netfront: MAC b2:11:11:11:11:11
backend not avalable, state=5
creating xenif0 failed: 22
It looks like the changes made in the fix for #767261, as mentioned in the
Debian changelog are the likely culprit:
[ Ian Campbell ]
* [xen] Backport various netback fixes (Closes: #767261).
However, I can't find a full final list of which fixes were backported.
Given that the last traffic on #767261 was on November 9th, I suspect at
least this upstream change from December 18 did NOT make it into the new
linux-image package:
xen-netback: support frontends without feature-rx-notify again
26c0e102585d5a4d311f5d6eb7f524d288e7f6b7 [2]
I can't verify this 100% as I don't know where in the archive I can find
the original 3.16.7-2 linux-image to downgrade to/compare the Debian diffs.
Should I reopen #767261 or file a new bug for this?
Thanks,
Martin
