tcpdump -y ieee802_11 will work in the basic senses, including the
code compilation for filters (where you may specify "link[]" to refer
to parts of the 802.11 header, as well as treat it like a normal
Ethernet header). Previously, it was just too far off to do anything
useful for us.
* While I'm here, fix some compile problems that will result from lex
and yacc namespace polution when linking with -lpcap. The namespace
is now "pcapyy*" instead of "yy*", and it tests fine with world and
some external applications that may or may not use "yy*".
