I updated the relevant parts of the V3 specifications at http://bcm-specs.sipsolutions.net - the pages for GPHY, B6PHY and B5PHY were changed. When I prepared a patch containing these changes, the speed of the BCM4306/2 for OFDM rates more than doubled. As an example, when iwconfig is used to set the rate at 36M, the TX rate increased from 6.8 to 15.8 Mb/s. Unfortunately, direct submission of my patch would violate the clean-room rules. Michael Buesch has other things that are more important. As a result, we need someone to look at the changes on the web page and prepare a patch for submission. I will be happy to test your submission. Larry
