Correct, it's not a "full router", it can route traffic to a specific LPAR if the IP address as been registered. If it has not been registered any packets received when a non-registered (unknown to any LPAR) address it will be dropped, unless you have defined one of the OSA's as a "PRIMARY ROUTER". If an OSA defined as "PARIMARY" ROUTER in one of the LPARS's then all traffic that is received on the OSA from a unknown IP address is passed to TCPIP on the designated LPAR and the TCPIP stack does the routing.
Not sure if it was true but I had heard that the I/O cards for the zSystems were single board computers using either x86 or PowerPC based CPU's and running some form of either OS2 (early on) or Linux (later on).
