Supports Cat9k in bundle mode only. For those unfamiliar, bundle mode means booting directly from a .bin image. Install mode, on the other hand, unpacks the image and performs other checks. Cat3k series install mode commands allow a delayed reload, but cat9k does not for some reason. Immediate reloads are not only inconvenient, but also make it harder to report install status in iosfw. Therefore iosfw only supports bundle mode on cat9k at this time.
