MFC r194570:
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.
