kni: remove ethtool support

Browse Source 
Current design requires kernel drivers and they need to be probed by
Linux up to some level so that they can be usable by DPDK for ethtool
support, this requires maintaining the Linux drivers in DPDK.

Also ethtool support is limited and hard, if not impossible, to expand
to other PMDs.

Since KNI ethtool support is not used commonly, if not used at all,
removing the support for the sake of simplicity and maintenance.

* kni: remove KNI ethtool support. To clarify, this is not to remove the KNI,
but only to remove ethtool support of it that is disabled by default and
can be enabled via ``CONFIG_RTE_KNI_KMOD_ETHTOOL`` config option.
Existing KNI ethtool implementation is only supported by ``igb`` & ``ixgbe``
drivers, by using a copy of kernel drivers in DPDK. This model cannot be
extended to all drivers in DPDK and it is too much effort to maintain
kernel modules in DPDK. As a result users won't be able to use ``ethtool``
via ``igb`` & ``ixgbe`` anymore.

Description
In order to support ethtool in Kernel NIC Interface, the standard Linux kernel
drivers of ixgbe/igb are needed to be reused here. ixgbe-3.9.17 is the version
modified from in kernel NIC interface kernel module to support ixgbe NIC, and
igb-3.4.8 is the version modified from in kernel NIC interface kernel module to
support igb NIC.
The source code package of ixgbe can be downloaded from sourceforge.net as below.

/*
* TBI_ACCEPT macro definition:
*
* This macro requires:
* adapter = a pointer to struct e1000_hw
* status = the 8 bit status field of the Rx descriptor with EOP set
* error = the 8 bit error field of the Rx descriptor with EOP set
* length = the sum of all the length fields of the Rx descriptors that
* make up the current frame
* last_byte = the last byte of the frame DMAed by the hardware
* max_frame_length = the maximum frame length we want to accept.
* min_frame_length = the minimum frame length we want to accept.
*
* This macro is a conditional that should be used in the interrupt
* handler's Rx processing routine when RxErrors have been detected.
*
* Typical use:
* ...
* if (TBI_ACCEPT) {
* accept_frame = true;
* e1000_tbi_adjust_stats(adapter, MacAddress);
* frame_length--;
* } else {
* accept_frame = false;
* }
* ...
