Overview of SLSA
Figure 2-1 shows that:

Data from an application is sent by TCP/IP or IPX/SPX into the SLSA QIO
segment of the processor.

From the queue, the data goes to a LIF where the data is associated with one of
the PIFs. The data then goes to a SAC, which gives the data the IP address of a
LAN.

From the SAC, the data moves to a PIF and is given a MAC address and sent to
the LAN. On the LAN, the data goes to its intended target.
Note. IPX/SPX is not supported on systems running H-series or J-series RVUs.
