PCI devices behind bridges in APIC Full Table mode

With 4.8-stable, I'm having a problem with IRQ routing when a device is
behind a PCI-to-PCI bridge in a PCI slot (like a dual-port NIC), when
using APIC "full-table" mode.  It appears that the kernel is not looking
at the mptable to determine the proper interrupt pin routing for these
devices.

Does anyone know if FreeBSD has support for this?  Can someone direct me
to the area of the kernel to examine?

Thanks,
John
