3c45889189 eal: remove exec-env directory
Only one header file (rte_kni_common.h) was in the sub-directory
	include/exec-env/
This file was installed in a sub-directory of the same name
in the makefile-based build.
Source and install directories are moved as below:

   lib/librte_eal/linux/eal/include/exec-env/
-> lib/librte_eal/linux/eal/include/

   build/include/exec-env/
-> build/include/

The consequence is to have a file hierarchy a bit more flat.

c6c36fe28a kni: fix build on Linux < 3.14
The atomic functions smp_load_acquire() and smp_store_release()
were introduced in Linux 3.14. Older kernels miss the functions:

kni_fifo.h:19:2: error:
	implicit declaration of function ‘smp_load_acquire’
kni_fifo.h:30:2: error:
	implicit declaration of function ‘smp_store_release’

The fallback is to drop the atomic barrier, as it was before
the commit below.

89397a01ce kni: set default carrier state of interface
Add module parameter 'carrier='on|off' to set the default carrier state
for linux network interfaces created by the KNI module.  The default
carrier state is 'off'.

For KNI interfaces which need to reflect the carrier state of
a physical Ethernet port controlled by the DPDK application, the
default carrier state should be left set to 'off'.  The application
can set the carrier state of the KNI interface to reflect the state
of the physical Ethernet port using rte_kni_update_link().

For KNI interfaces which are purely virtual, the default carrier
state can be set to 'on'.  This enables the KNI interface to be
used without having to explicity set the carrier state to 'on'
using rte_kni_update_link().

With kernel 4.19 ethtool_ops `get_settings` & `set_settings` are
replaced with `get_link_ksettings` & `set_link_ksettings`
Commit 9b3004953503 ("ethtool: drop get_settings and set_settings callbacks")

This fix practically removes `get_settings` & `set_settings` support
for the kernel versions that have the new ethtool_ops without
implementing the new ones.

12ce2da88f kni: return failure for all ioctls
Modify kni_net_ioctl() to return -EOPNOTSUPP for all ioctls instead
of 0.

This is necessary because the Wicked (and possibly other) network
interface managers will perform the SIOCGIWNAME ioctl to check if
the interface is a wireless interface.  If the KNI module returns
success, Wicked will incorrectly interpret the interface as a wireless
interface.

e77fec6949 kni: fix possible mbuf leaks and speed up port release
rx_q fifo can only be released by kernel thread. There may be
mbuf leaks in rx_q because kernel threads are randomly stopped.

When the kni is released and netdev is unregisterd, convert the
physical address mbufs in rx_q to the virtual address in free_q.
By the way, alloc_q can be processed together to speed up the
release rate in userspace.

In my test, it is improved from 300-500ms with a mempool that has
 131072 mbufs to 10ms(regardless of the specifications).
