I wonder what the host network properties are.
Does tcpdump reveal just how big those too-big frames are?
VirtualBox is running on Windows 7 (don't get me started) which reports
Intel(R) 82579LM Gigabit Network Connection
That is connected to a Cisco IP Phone 7975, which supports Gigabit. I don't know what the phone is connected to but that switch probably has fibre to the backbone.
Here's some data on the frame size:
grep oversize /var/log/messages | sed 's/.*atom//' | sort -u
/netbsd: wm0: discarding oversize frame (len=1434)
/netbsd: wm0: discarding oversize frame (len=595)
/netbsd: wm0: discarding oversize frame (len=662)
/netbsd: wm0: discarding oversize frame (len=678)
/netbsd: wm0: discarding oversize frame (len=746)
grep oversize /var/log/messages | wc -l
54
Does that help any?
