(Presumably the single-bit members would all be at the beginning of the structure, so that they get packed into a 
single word.)

The reason I went that way was to let all the bits be cleared with a single assignment.  I suppose we could memset the 
entire union.

(BTW, it's not as if the only ones are for 11n and 11ac; each PHY that has additional information to provide has a 
member of the union.)
