Hi, We found the problem. It was a little/big endianness problem.
It seems that with our cross-compile toolchain __BYTE_ORDER == __LITTLE_ENDIAN is not true even if the system is little endian. Probably one of both of these are not defined or not defined correctly. This caused the wrong function to be used in ieee802_11.h. This in turn caused frame_control = ieee_order(frame->frame_control); to invert bytes. That's it. I hope this didn't create too much noise on the mailing list.
