Subject: ieee1394: extend lowlevel API for address range properties
From: Stefan Richter <stefanr@xxxxxxxxxxxxxxxxx>
Host adapter hardware imposes certain restrictions and features on address
ranges. Instead of hard-wiring such ranges into the ieee1394 core or even
into protocol drivers, let lowlevel drivers specify these ranges via struct
hpsb_host.
