Worth a try, but I don't think it will make a difference. I had that
code once (it should even be visible on the svn history) but removed
it because it isn't required, the 6005 series devices work very well
without it (I'm using a 6230 (6000g2b) daily) without issues. What is
import though is which calibration results are sent to the runtime
firmware, I suspect there might be an issue in
iwn5000_rx_calib_results() around IWN5000_PHY_CALIB_DC.

I remember that someone reported the 6250 devices working once, it
might be worth going over the last revisions (there where some
calibration related changes) and figure out which one broke it.
