In linux kernel since version 2.6.34 (release Date: 2010-05-16)  
This option generates an internal data structure representing
the wireless regulatory rules described in net/wireless/db.txt
and includes code to query that database. This is an alternative
to using CRDA for defining regulatory rules for the kernel.

Using this option requires some parsing of the db.txt at build time,
the parser will be upkept with the latest wireless-regdb updates but
older wireless-regdb formats will be ignored. The parser may later
be replaced to avoid issues with conflicts on versions of
wireless-regdb.

Most distributions have a CRDA package. So if unsure, say N.
