This series fixes two critical xen-netback bugs.

1. Netback may consume all of host memory by queuing an unlimited
number of skb on the internal guest Rx queue. This behaviour is
guest triggerable.

2. Carrier flapping under high traffic rates which reduces
performance.

The first patch is a prerequite. Removing support for frontends with
feature-rx-notify makes it easier to reason about the correctness of
netback since it no longer has to support this outdated and broken
mode.
