I recently found some places where the G-PHY initialization
specifications were wrong. 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
