My FreeBSD machine acts as a firewall with ipfw and natd for a Windows bo=
x=20
behind it. When users on the Windows box use their browsers extensively, =
I=20
get messages like

dc0: TX underrun -- increasing TX threshold
dc0: TX underrun -- increasing TX threshold
dc0: watchdog timeout
dc0: TX underrun -- increasing TX threshold
dc0: TX underrun -- using store and forward mode
dc0: watchdog timeout

(dc0 is the interface to the Windows box).

What does this mean, and is there anything wrong that needs to be fixed?=20
