does lucid not have ethtool

[Tapas Mishra]

I was reading a book for network device driver development and it
mentioned about methods
ethtool_ops in include/linux/ethtool.h
upon checking the above file I did find that method.
At this I thought of trying some thing on my laptop and I then found
that ethtool is not installed.
Hence I checked http://packages.ubuntu.com/lucid/net/
and I did not find ethtool even there.The bad part is on the above
link I don't even find a search option
I am trying to understand how NIC driver is tied to ethtool utility.
Any pointers for that?
