Incidentally, this means that dual-band drivers now absolutely need to take a look at the scan channel list that is provided since if they ignore it they will end up doing two full scans instead of one. Since wl1271 is the only driver this affects right now, and its 5ghz support is disabled, this seems ok to me. johannes --=-08SEybUe1v0eiqRb+sRX Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJK51cBAAoJEODzc/N7+QmaJZsP/2qFfbMYFk85e0/q2ELSnm4T CsgfZwuBzv6xKUaqGbXKGwaMH3sPnjFwS8m7Fhg60JXjG2cow5W9D4Uwtd4wO/dB +v8Br59/kHlSIvU8u2FTpZfjAWVK0w0utvCL9Dc+9D8c/aM+H+9IuroAKdv1ItY2 cD+1fglqfZjryF80vl9U20cTPZrV15gqYQoX8dYMWw16wK8HQzjnt+RRm+GZ/nGd oIdxCx+E7PoJB8oeLbK7j4kX+kx971+ciRrasjDRcy6+bgrl+dj0/PuavP27oVxb 4RtraQiD1ArWt5rND7k2ANg6finQZdZk7jvAHZsGanhM6Pz3LHMVSZbI3oaPj+jl l1QUs7yn7869eb/n+hxUQGvH1mCWVwoGjOfMSqMaInBjpfRXf3LqZEw4Dd0WEef/ ONsStPbMns0r0of3c8B8JguNdsTbOYpPcmMcQxPeul1bWrH4m0nIslNH8fet1w3K i1fbJFL0zRV4xxP6bZc7JDo6Zi1Upg2PK7H0spWXOJbc903Z/P/G24dCjEHloMsl Ys9SQr8ZA5wKbdLbWvZeCs3m2NtZfQwZwhYxE0pWg2vo8v23j2xUsoUHisYNWx86 ep1ckYC4GL6yCOGHU9tb0JLlPqqkshhFjW9i5apgT2y8fwtOP3RLA+eTeJl6QIFr fnQIfBrgHuPzlXGXD2Vc =BvtP -----END PGP SIGNATURE----- --=-08SEybUe1v0eiqRb+sRX--
