reverted the code to support software filtering for chained incoming packets,
as that code was not working.

Network stack is fixed now.
HTTPERF is working on both LMP and UMP communication channels.

Software filtering now supports chained packets
This does not yet work together with IP fragmentation

create mode 100644 include/net_interfaces/flags.h

partially working version when everything is running on default core.
The current execution is **very** slow as everything is in the same core,
leading to large number of context switches.

partially working version

modified loopback driver to work with ump based interface.
Also removed all the code from queue_manager which was using bulk_transport

Added local loopback device

Extended queue manager library interface to allow for queue termination
This is not implemented yet, but it will be used in the ethernet latency
benchmark, so multiple runs can be done without reboots, might also be
useful in the future when queues are handled more dynamically.

Added ethersrv_argument() call for net_queue_manager interface
This method is inteded to be called by the driver on all command line
arguments it does parse itself. The idea is that driver independant
stuff like memory affinity etc. can be done in the library, also this
might be useful in connection with benchmarks.

Simplified TX path of net_queue_manager interface to driver
This is an attempt to simplify the driver interface and push the
complexity into the library, more precisely it removes the need for the
driver to know about the bulk transfer mechanism. This also simplifies
the future implementation of benchmarks using this interface directly.

Moved managing of RX buffers to net_queue_manager library
This step is necessary for hardware filtering, since there we need to
tell the card directly the addresses of the buffers in the bulk transfer
ring. But with SW filtering the library only allocates some intermediate
buffers, from where the packet is then copied to the right buffer.

Renamed interface ether_control to net_soft_filters.
Also, rearranged the code and renamed files to match with new interfaces.
Modified the hake/RulesDefs.h to simplify the dependency capturing for
net_queue_manager related code.
