Hi Kalle/Jeff,

Any new input on this so I can move forward on fixing this ?
Otherwise I think I'll end up going on with Jeff's proposal of only using the
bitfield for intra driver representation & then converting the bitfields to
their corresponding WMI_SCAN_XXX when transmiting the req to the hw with wmi.
