Each MAC address should be only assigned to one link at a time.
If the motherboard EEPROM is messed up, it might happen that
there are more links connected to a single MAC.
So in that case a
[link_index] = ip2.link_lookup(address=mac_addr)
results in a ValueError (too many values to unpack) which gives
no clue on what actually went wrong. Instead we check the len
of he link_lookup result and give a more meaningful error message.
At this point, only about half of the mpm methods work on the simulator
over the mpm shell, and it hasn't been tested with uhd at all.
If you want to give it a try, first install all of the python
dependencies of mpm (The simulator doesn't require libusrp or any of
the C++ deps). In addition, running mpm on a desktop machine requires
the python lib netifaces. Next, make an /mpm/build directory and open
it. Run `cmake .. -DMPM_DEVICE=sim`, then `make`. Finally, run
`python3 python/usrp_hwd.py`. You should be able to open another
terminal and run `mpm/tools/mpm_shell.py localhost` to connect to the
mpm server.

The sysfs call used to determine link speed occasionally will fail and
return -1. In order to mitigate side effects from this behavior, return
10 Gbs link speed instead of 1 Gbs. This mitigates problems that occur
when this issue is seen on 10GbE ports. This approach was elected over
returning -1 to be handled on the host side in order to avoid breaking
mpm compatibility.

This changes MTU handling for the "internal" UDP type. Because MPM
echo packets will not be returned for internal NICs, use the iface's
programmed MTU instead.
Because the detection of valid Ethernet devices happens across multiple
calls in a non-atomic fashion, we cannot assume that a device passed to
net.get_iface_info() actually has a valid IP address, so we don't make
that assumption.
- Moved nijesdcore to cores/
- Moved udev, net, dtoverlay, uio to sys_utils/
- Made all imports non-relative (except in __init__.py files)
- Removed some unnecessary imports
- Reordered some imports for Python conventions
