hs_eth_function and fs_eth_function seem unused in ether.c

I'm trying to understand ether.c in order to better integrate pxa27x_udc 
with it. My goal is to make MCCI, Belcarra, and Jungo Windows CDC 
Subset/SAFE/MDLM drivers talk with a Linux PXA270 embedded device with 
TCP/IP.

Reading thru several versions of ether.c from the Linux kernel (as early 
as 2.6.10 and as late ast 2.6.21.5) tree and from what Grahame Jordan did 
(a version enable a PXA255 do MDLM/SAFE) I see a consistent weirdness: The 
arrays hs_eth_function and fs_eth_function seemingly do not get pointed at 
by ether.c. In a few kernel versions I even searched all routines in the 
/drivers/gadget/drivers directory and could not find them used. These are 
static arrays and so I would expect them to get referenced in ether.c. Not 
so.

So why are these arrays in ether.c?

Also, the usb_endpoint_descriptors that each array has pointers to do not 
get referenced anywhere else. So there's this mystery: How are all these 
endpoints getting used?

Maybe I'm being dumb and missing something obvious...
