That sounds good to me.

Presumably a "global" option is overridden by per-interface options,  
e.g.:

	dumpcap -s 96 -i en0 -i en1 -y IEEE802_11_RADIO_AVS -s 128

would capture on en0 with a snapshot size of 96 and the default link- 
layer type and on en1 with a snapshot size of 128 and a link-layer  
type of IEEE802_11_RADIO_AVS.

What happens with multiple -i options and the -L option?  Does it  
list, for each interface, the available link-layer type values, or  
does it fail?
