["Joshua (Shiwei) Zhao" <swzhao@xxxxxxxxx>]

Under the Capture Options dialogue, there is an item for "Link-layer
header type". There are only two menu items as default: "Ethernet" and
"Data Over Cable Service.....".
How can I add another type there, e.g. 802.11, either by configuration
or by modifying the code?
And how can I modify the code to add other types to always show up by default?

Many thanks,
Joshua
