  Modified files:
    sys/net              if.h 
  Log:
  Add IFF_NEEDSGIANT to IFF_CANTCHANGE, to prevent user-level code
  from clearing the IFF_NEEDSGIANT flag on Giant-locked interfaces.
  In particular, wpa_supplicant was doing this on USB interfaces,
  causing panics when Giant-locked code was then called without Giant.
