I think these commits, which are in v3.18-rc3, are probably the ones:

ecf08d2 xen-netback: reintroduce guest Rx stall detection
f48da8b xen-netback: fix unlimited guest Rx internal queue and carrier flapping
bc96f64 xen-netback: make feature-rx-notify mandatory

I'll investigate a backport/check if they are destined for stable@.

Ian.
