Subject: rapidio: fix default routing initialization
From: Alexandre Bounine <[email protected]>
Fix switch initialization to ensure that all switches have default routing
disabled. This guarantees that no unexpected RapidIO packets arrive to
the default port set by reset and there is no default routing destination
until it is properly configured by software.
This update also unifies handling of unmapped destinations by tsi57x, IDT
Gen1 and IDT Gen2 switches.
