Its what makes sense if you think about it. I'm not really too sure the intersection makes most sense, we mostly used the first hint because it's likely to be from the built-in card, ergo announcing a region for which the whole product was certified. If you add a card, we basically don't trust it currently. > My suggestion is to add a default minimal 5 GHz regulatory domain > definition to your driver on single band cards to deal with this.

This might work with systems built purely out of Intel cards, but to be honest, I wouldn't want to see this because it would mean that if you add a dual-band prism54 USB then it'll start sending on those 5 GHz channels regardless of where you are and what you're allowed to do. johannes --=-oC9k9gb3sKcfYD6HCAvi Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIcBAABAgAGBQJI9iwtAAoJEKVg1VMiehFYuNEQAIWNREasnzmAlGQu1Gh0FvOY i4RqtLojFtDkJ578G6Z3jrzdx4LyDkdmcXbBoTBWJSPVwqzRIPrE7ggu0NBtjdse ld4L4MmIxdZqZhoHxtAlSChiShsN9UEdH9NFNbmcv3qED1aNkJqAooLgrgF64B8u yRQ6oXzqpNglPBPPwBssfUVOM5RYYmGI76hFARyz5aRyd4hDHyztL46mmPRiwMhG IWLDoKEWOQy25NzT2LMCvvZ74F3gjxxcGMdLbsE01etbk6PhpLoxoNgHrilZATEA 7HlfAlw62lcVLzxDubPk+9vwsUhzk0lvBaB65yF4qODwuIniUALwLc45wpdCmApX RSKBtrb97aqCiRSbjvUuDGFteUSIM1QruD1FonOnivftXvzXV7+1a3wu2T7DjAbK iSO783Q3bVKXSZJZFwM11in/6ilXOBvoGRv5TNMJ3LzXgt9n4HRJahu+SGFJ83n+ WQPHwNgW5ymfca7aAMM0ym0PObIa4Jymiz72ejUsxU+iIFipvOzAD6An+kNhve8r U85av4Z+REFTQ4oCTCsbsF+IiNUY6wYA7muUDDFcKeVVO+eUPCOj706M5ihThNHu 5M0ZNn6r3YBwofk4QUvMpmSgBB7GznAPgb02nuFHX/0paVbZ8dg+MUl2HSsp9bSP JTEVX7caiaY6ebU3WblY =Ibh7 -----END PGP SIGNATURE----- --=-oC9k9gb3sKcfYD6HCAvi--
