Description of problem:

  At present, the GlusterFS testing framework uses tcp for all tests, as there
  is no "protocol $PROTOCOL" line in any of the volume creation commands.

  We should add a protocol specifier to the volume creation commands in our
  testing framework, which would enable us to test RDMA as well.


Version-Release number of selected component (if applicable):

  Upstream GlusterFS git, master branch as of Tue 2nd July 2013.


Additional info:

  Initial support should be very easy to add without breaking the existing
  testing framework.

  Likely starting by adding the PROTOCOL definition to tests/include.rc:

    PROTOCOL=${PROTOCOL:=tcp};    # transport protocol to use

  Then adding "protocol $PROTOCOL" to the volume creation commands in:

    tests/basic/*.t

  Adding "protocol $PROTOCOL" to other tests could be done at a future point.
