After looking at the standard, it became clear that it is only the 72
Mbps rate that's creating the havoc:

It will be put in the extended rates, but since 72 * 2 is 144, it will
overflow the data rate field and set the basic rate flag/MSB, causing
the bogus 8 Mbps "basic" rate.

I'll respin this patch with just removing the 72 Mbps rate.
