Summary:                    [patch] Support for generic HFC-4S cards
Description: 
A patch to add some basic support of other HFC-4S -based PCI cards (such as
the ones made by Junghanns). 

Status: gets rid of the echo canceller messages when not needed, but still
needs work.

Specifically:
* It adds too broad a range of cards (which also include bero.net cards) 
* The range may include some 2-ports cards, which will probably not work.

Not yet tested to work, though it it is at least configured.

i think the code must be modify to support other HFC bri cards. in ec_write
method
=====================
static void b4xxp_setleds(struct b4xxp *b4, unsigned char val)
{
	ec_write(b4, 0, 0x1a8 + 3, val);
}
======================
i think most of other cards are different from Digium in term of hardware
design. they are:
1) hardware based echo cancellation
2)  using cpld in digium, but others do not use that.
so the extra code should be add to support LEDs of other HFC cards.
