fxp entering promiscuous mode causing link to bounce

JFYI I see this on an ancient i386 system I have, running 9.0-RELEASE:

fxp0: <Intel 82801BA/CAM (ICH2/3) Pro/100 Ethernet> port 0xac00-0xac3f
mem 0xefdfe000-0xefdfefff irq 11 at device 8.0 on pci1

Same thing...going into or out of promiscuous mode makes the link bounce.

fxp0: link state changed to DOWN
fxp0: promiscuous mode enabled
fxp0: link state changed to UP
fxp0: link state changed to DOWN
fxp0: promiscuous mode disabled
fxp0: link state changed to UP
