Title:
  DPDK init scripts need some hardening against broken specifications in
  /etc/dpdk/interfaces

Status in dpdk package in Ubuntu:
  Triaged

Bug description:
  While testing it became obvious, that while working we need some more
  resiliency and user friendly messages in case something goes wrong.

  Today we have cases like:
  - forgot the bus spec -> just doesn't do anything (silently)
  - wrong pci ID -> fail to start the service in general
  - no module specified -> fail with unclear modprobe error (due to empty name)

  The init script needs some hardening and better error messages.
