Subject: [PATCH v2 0/6] fix ethdev device detach

Device detach in librte_ether is rough right now.

 - Device hotplug capability is not properly checked
 - Device state should be set after a successful detach
 - MLX drivers are lacking the relevant flag
 - And this flag should actually be removed, thus occuring an API change
   for v17.11. An announce follows.

Without this series on an MLX4 port:

   testpmd> port close 0
   Closing ports...
   Port 0 is now not stopped
   Done
   testpmd> port stop 0
   Stopping ports...
   Checking link statuses...
   Done
   testpmd> port close 0
   Closing ports...
   Done
   testpmd> port detach 0
   Detaching a port...
   testpmd> show port info 0
   Segmentation fault (core dumped)

With this series:

   testpmd> port stop 0
   Stopping ports...
   Checking link statuses...
   Done
   testpmd> port detach 0
   Detaching a port...
   Please close port first
   testpmd> port close 0
   Closing ports...
   Done
   testpmd> port detach 0
   Detaching a port...
   Port '00:03.0' is detached. Now total ports is 0
   Done
   testpmd> show port info 0
   Invalid port 0
   Valid port range is [0]

v2:

  - remove coredump from patchset
