Intel 7260 - limited in 5GHz spectrum

Hi,

I've been working with the Intel 7260 card which advertises itself as
dual band wireless AC card. However, I cannot get it working in AP
mode in the 5GHz range. An $(iw list) shows that the entire 5GHz band
has 'no IR' next to it so as not to allow device radiation (please see
pastebin here: http://pastebin.com/T4BWnBmn).

After searching around the internet a bit, it seems that the card
doesn't allow for this mode (And is thus not really dual band?). I'd
like to know if this is a firmware limitation and if there's a fix in
place, or if not, why is this card limited to the spectrum it can
radiate at?

Thanks,
