To get them you have to execute an NDA with Broadcom.  So we're
effectively limited to what can be gleaned from the Linux driver.  Its
header file has a struct declaration for the "T3_EXT_RCV_BD" (extended
receive buffer descriptor, probably) but the driver doesn't actually
use it.  Without the docs it would take a lot of trial & error to
figure out how to make it work.

In other words, I doubt that the bge driver could use a new buffer API
unless it provided a way to get physically contiguous buffers.
