====================
selftests: rds selftest

This series is a new selftest that Vegard, Chuck and myself have been
working on to provide some test coverage for rds.  I've modified the
scripts to include the feedback from the last version, but let me know
if there's anything missed.  Questions and comments appreciated.

Thanks everyone!

Allison

Changes in v2:
- Removed qemu vm creation and related code
- Updated README.txt with examples of running the test with virtme
- Removed init.sh. run.sh now directly calls test.py
- Some clean up done with the return code handling since there is no
  vm between the scripts anymore
- Imported ip python function in
tools/testing/selftests/net/lib/py/utils.py into test.py
- Adapted test.py to use the imported ip function, and removed the
local ip wrapper
- Some line wrap clean up
- Link to v1:
