Using Option 43 Info FROM a Cable Modem Client to Define a Class

Thanks for the added info David, which actually is in the DHCP handbook
appendix B on page 456.  Also, thanks to Glenn for pointing out
encapsulation info in the Man Pages.  I missed the boat on both counts,
probably because both only talk about sending encapsulated data, not
DE-encapsulating incoming data.

So I have 2 different ways to accomplish creating a class based on
Suboption 2 of Option 43 info received in a DHCP discover message:

*****************************************
option space SA;
option SA.devtype     code 2  = text;
option SA-43 code 43 = encapsulate SA;

class "eCM" {
	match if option SA.devtype = "ECM";
{

or

option space SA;
option SA.devtype     code 2  = text;
option SA-43 code 43 = encapsulate SA;
vendor-option-space "SA";

class "eCM" {
	match if option SA.devtype = "ECM";
{
*******************************************

or 'vendor-option-space "SA";'
