The series of patches are for doing basic tests
of NIC driver. Test comprises checks for auto-negotiation,
speed, duplex state and throughput between local NIC and
partner. Tools such as ethtool, iperf3 are used.

Changes in v3:
- LinkConfig class is included in the hw library. This contains
  generic APIs for doing link layer operations.
- Auto-negotiation checks involve changing the auto-neg state
  both in local and partner NIC.
- Link layer test and performance test are separated to 
  different selftest files.
- Resetting of NIC driver done after test completion.

Changes in v2:
- Changed the hardcoded implementation of speed, duplex states,
  throughput to generic values, in order to support all type
  of NIC drivers.
- Test executes based on the supported link modes between local
  NIC driver and partner.
- Instead of lan743x directory, selftest file is now relocated 
  to /selftests/drivers/net/hw.
