Hi All,

The following patches are to fix a problem with detaching a KNI
interface using rte_kni_release and to add a new API function
to allow users to change the link status (up/down, speed, etc)
of the interface in the linux kernel.  In previous versions, it
was impossible to release a KNI interface without waiting for the
timeout in kni_net_process_request to expire if the interface is in
the UP state.  The solution to this issue was to separate the process
of releasing the netdev device from the linux kernel from actually
freeing the KNI interface in the kernel and in the RTE library by
introducing a new API function, rte_kni_free().

The last patch : 'kni: add API to set link status on kernel interface'
adds a new API function to allow the DPDK user to change the link
speed and status reported by the netdev in the linux kernel.

This resolves issues with allowing automatic network configuration
applciations such as NetworkManager to assign addresses and for user
space applications to be able to open sockets on these interfaces,
as some operations rely on the link status being up before they
work properly.

This last patch is included in this series because both new "features"
introduce new ioctls to the rte_kni kernel module, so the order in
which the patches get applied affects which number each new ioctl gets.
I thought it better to bundle them together to try to get them applied
as a series to avoid any issues with this.

Please have a look!

thanks
dan
