That sounds good to me.
This is what I had initially in mind. However, ordering of the
arguments is then important, as some dislike. However, I like
this ordering related stuff more than the comma separated -i args...
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?
I would just fail them. I actually would require an -n option before
the second -i. We will only support capturing from multiple interfaces
when using PCAPNG...
