New Revision: 186100
URL: http://svn.freebsd.org/changeset/base/186100
Log:
Improve regdomain.xml parser:
o store XML_Parser in the state block so we can report line numbers for errors
o complain about netband w/o mode
o complain about unknown modes
o complain about band w/o enclosing netband
o complain about duplicate freqband
o complain about unknown channel flags
o complain about band w/o freqband's
o complain about band w/o maxpower
o complain about country w/o ISO cc
o complain about country w/o regdomain reference
