>Description:
	fpa0, as of recently, is correctly detected:

fpa0 at pci1 dev 3 function 0: DEC DEFPA PCI FDDI DAS Controller
fpa0: FDDI address 00:00:f8:4a:15:b1, FW=2.46, HW= , SMT V7.2
fpa0: FDDI Port[A] = A (PMD = ANSI Multi-Mode), FDDI Port[B] = B (PMD = ANSI Multi-Mode)
fpa0: interrupting at ivec 18

	however when the interface is started -- i.e. 'ifconfig fpa0 address' or
	'ifconfig fpa0 up' -- a panic ensues:

# ifconfig fpa0
fpa0: flags=8822<BROADCAST,NOTRAILERS,SIMPLEX,MULTICAST> mtu 4470
        address: 00:00:f8:4a:15:b1
        media: FDDI Multi-mode dual-attach
        status: no ring
# ifconfig fpa0 192.0.2.1 up
load_mbuf: dmamap sglen 0 != len 800
