...so I'm moving this to wireshark-dev. (There is no reason to expect
that any work will be done on 802.11n in Ethereal; the work will be done
Is anyone working on 11n support for the capture filters or file formats?
Is 802.11n similar to 802.11b, 802.11a, and 802.11g, in that
the link-layer header is the standard 802.11 header;
any additional protocol changes are in the form of, for example, new
frame types or new tagged values?
If so, then little if any change to libpcap should be needed for capture
filters (capture filters are *NOT* implemented by Wireshark, they're
implemented by libpcap), and there shouldn't be *any* need for a new
file format (802.11, 802.11b, 802.11a, and 802.11g are handled by the
exact same file formats).
With bursting, capture filters will probably be difficult, if not
impossible, to implement unless a burst of packets is broken up into
individual packets, individually handed to the capture mechanism, so
that the filters act on each individual packet in the burst.
