Thanks for pointing this out. However, the proposed order is not
correct; the IEs are _not_ in numerical order by the id. The order for
them is defined separately for each management frame subtype in IEEE
802.11, 7.2.3 tables.

I moved WMM IE (vendor-specific) to the end of the frames and HT IEs bit
further down the (re)association response frame, but did not move
extended supported rates IE or separate HT IEs as proposed in your patch
since I do not believe that they would match the order described in the

It is still possible to get WPA IE in incorrect place (fixing that
requires some more effort than just moving function calls), but other
IEs should now be in more or less correct order.
