It worked for me, but YMMV. Yes, it's a bug in the early chips - supposedly fixed in later steppings. The "official" workaround for the defect is to do what you're doing, but in the driver. Basically, if you don't see any packets come in over a period of a few seconds, then reset the card (actually, reprogram the multicast filter, but this requires re-initializing the card). I thought this was disgusting so I never implemented it. Sigh. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
