Help text

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.

For details see:

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