    LinuxKPI: 802.11: enable fragmentation offload
    
    Let the hardware handle fragmentation itself and tell net80211 to
    save itself from it.  We already call the (*set_frag_threshold)
    mac80211 function.
    
    This should be a NOP for all currently enabled LinuxKPI based WiFi
    drivers.
