That 18 Mb/s receive rate was observed data transfer from my server
that is wired to the router/AP and over the air to the BCM4312, just
as the 11 Mb/s was observed transfer from the BCM4312 to the server. I
have no idea what bit rate was set into the interface. Every time I
looked, it was at 1 Mb/s, but the throughput is better than that.

I missed those (obviously). Are there any other places in the LP PHY
that need work?
