validates the Bus Number from the Requester ID of
upstream Requests against the secondary subordinate
Bus Numbers.

addr:
Bits 31:20 are assumed to be 0xFECh. Bits 8:0 are a don’t care for address
decode. Address decoding to the APIC range is done as
APICBASE.ADDR[31:8] <= A[31:8] <= APICLIMIT.ADDR[31:8].
Outbound accesses to the APIC range are claimed by the root port and
forwarded to PCIe, if bit 0 is set, even if the MSE bit of the root port is clear or
the root port itself is in D3hot state.
