Incorrect MAC used if LAN3 is used instead of LAN2 about motoros2

[gavanderhoorn]

Looks like this:

motoros2/src/CommunicationExecutor.c

Lines 62 to 68 in 8c1a524

	//Construct the RMW Micro-XRCE-DDS client key to use
	//Use MAC last 4 bytes as client key (1 byte from the OUI, 3 bytes from NIC)
	UCHAR macId[6];
	motoRosAssert_withMsg(
	Ros_GetMacAddress(macId) == OK,
	SUBCODE_FAIL_MP_NICDATA,
	"Must enable ETHERNET function");

and this:

motoros2/src/ConfigFile.c

Lines 130 to 137 in 8c1a524

	//node_name
	UCHAR macId[6];
	motoRosAssert_withMsg(
	Ros_GetMacAddress(macId) == OK,
	SUBCODE_FAIL_MP_NICDATA,
	"Must enable ETHERNET function");
	//last three bytes of MAC ID are a unique identifier
	sprintf(g_nodeConfigSettings.node_name, "%s_%2x_%2x_%2x", DEFAULT_NODE_NAME, macId[3], macId[4], macId[5]);

should first figure out which NIC to retrieve the MAC from.
