/**

Test IPv6 Static DNS Configuration for different NIF's

  This routine contains common base class code for tests in

  section 28.

	The test is used to check that a particular NIF is taking

	into account the following CommDb parameters:

		Ip6DNSAddrFromServer

		Ip6NameServer1

		Ip6NameServer2

		  Basic strategy:

			1.  Retrieve configuration information from ini file (IAP, DNS addresses)

			2.  Start the NIF to test via RConnection

			3.  Retrieve the interface binder names (via RConnection KConnGetInterfaceName)

			4.  Retrieve all TCP/IP interface information (via KSoInetNextInterface socket option)

			5.  For each interface retrieved in (4), match its name against the names retrieved

			in (3) (to find the TCP/IP interface(s) corresponding to the RConnection) and

			ensure that its DNS addresses match those in the Ini file (which, in turn, match

			those in the CommDb).

			  The test code in this routine is executed for each Test 28 substep.

			  Each substep is used to test a different NIF, with the aSubStep parameter being used

			  to index into a different section of the ini file to retrieve the parameters

			  needed for the particular substep (in particular, the IAP to start).

				@param aSubStep Sub step number
