That's actually what people suspected when I asked around at the summit, and it seemed the general consensus is that we need a proper setting for that in nl80211 along with some of the roaming capability exports. So until that happens, the last patch won't get in anyway, and we'll see about the NEED_... stuff later. johannes --=-2ak1OS88rXZrt71HcrPN Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJKSHzgAAoJEODzc/N7+Qmat9QQAMgB5wq0s4gxS7C2auWp8fSy QJizex7jDgH1DeFOBTH7E+9ungwGvIKE57AFM//oqzyjcPm+mO37bL3kcce4Ll6V QNFr1yIEB8+LtxZKfBNO29X2IQWCn9OFVfw3ASw3h1+lnRIZv8IiJKwyjADtoIL8 jhAUovT/5m/MuQXoUSNhOmZfLHvV/wrCvBBOkmZBaqrW3CJn4rCDO9AuvXwNZnCW wE52qHjidyka5eP/V4ykIXgYQ8lecRrWlY2vXJfwew/DFOuWr4jMSsEmlzu740bd RVdvdVFdoWFmokEQBT6pYev+WVLYHcvSfID5ROlEcgnqYKHJihAf2M2zucjt/ZdH HQh9F3X402A4CxkiD9EpOW+I2l28EzELNpRBlW49GgGOuozazlwwmW3s0hPDIogz JBmG5jOa9FrYYVnDrEEjoaqA448O/O8q3tiDWbrOTuXHQF9/+1NSKjyQHHJUg804 f6hmBy9hhDbxOW+bBI9V01cP7UIIIKGCt61gQIL2WDPzZ3XqbS9fG+vPdUAEd/vt dbzGyHGNbVCt5yTa1nRNn8Y0ZnGIy7BO4D7UdWsXrgbdM6W3Cb10eczXfyK05/kH cr9XxRMjlTbXISvgBBoowcvGdEq9pKjQQIeIVFLMfas7QUEhudD9CyxeZWC6bhXx GVj5iny9+N+cvN/kHMz9 =RXFu -----END PGP SIGNATURE----- --=-2ak1OS88rXZrt71HcrPN--
