Due to possible PCI bus lock-up issues fxp(4) didn't perform full hardware reset in attach phase. Selective reset does not clear configured parameters so I think full hardware reset is required. To prevent PCI bus lock-up, do selective reset first which will get off the controller from PCI bus and request software reset after selective reset. Software reset will unmask interrupts so disable it after the reset.
