35 switch is provided by SSLBIS subtable. This provides the bandwidth and latency
62 Bandwidth in this example is calculated as such:
63 B(EP0) - Bandwidth from EP0 CDAT DSMAS+DSLBIS
64 B(L1) - Link bandwidth between EP0 and SW0DSP0
65 B(SW0) - Bandwidth for the switch from SW0 CDAT SSLBIS.
66 B(L0) - Link bandwidth between SW0 and RP0
67 B(RP0) - Bandwidth from root port to CPU via SRAT and HMAT (Generic Port).
