Subject: rapidio: add new sysfs attributes
From: Alexandre Bounine <alexandre.bounine@xxxxxxx>
Add new sysfs attributes.
1. Routing information required to to reach the RIO device:
destid - device destination ID (real for for endpoint, route for switch)
hopcount - hopcount for maintenance requests (switches only)
2. device linking information:
lprev - name of device that precedes the given device in the enumeration
or discovery order (displayed along with of the port to which it
is attached).
lnext - names of devices (with corresponding port numbers) that are
attached to the given device as next in the enumeration or
discovery order (switches only)
