Colin Percival 2187ec93ad pci: Add hw.pci.intx_reroute sysctl/tunable ... INTRng can leak resources when INTx interrupts are re-routed, which is typically harmless but can be fatal when devices are (repeatedly) hot plugged into PCI buses on INTRng systems. Re-routing INTx interrupts is nonetheless still necessary on some systems, and identifying whether the re-routing should be enabled or disabled seems to be nontrivial. Add a hw.pci.intx_reroute sysctl/tunable so systems which don't want legacy PCI interrupt re-routing can turn it off. This is probably not the best fix but it's something which can be safely included in FreeBSD 14.3.
