I've been struggling to get a good understanding of the radiotap header
format and structure for the past few weeks, so I thought I'd contribute
some documentation to the Wiki in an attempt to save anyone from going
through the same pain in the future:

http://madwifi.org/wiki/DevDocs/RadiotapHeader

One issue I am still unclear about is the requirement to align data to
natural word boundaries - since there is no way to "pad" a field, the
only option for alignment is to include 8-bit fields that are not
otherwise needed (such as the wr_flags field in the current
implementation).  Unfortunately, there is no way for the parser to know
that a field that is present is not in use and only present for boundary
alignment.  I've asked David Young to comment on this issue.

I'll be submitting another patch to fix the remainder of the
byte-ordering issues.  If you want to ignore ticket 500 for now, I'll
update the ticket with a patch that includes support to report the TSF
timestamp as well as fixes for the byte-ordering.

Comments/edits on the wiki page are most welcome.  Thanks,

- -Josh
