    mac80211: reorder some transmit handlers



static ieee80211_tx_handler ieee80211_tx_handlers[] =
{
	ieee80211_tx_h_check_assoc,
	ieee80211_tx_h_sequence,
	ieee80211_tx_h_ps_buf,
	ieee80211_tx_h_select_key,
	ieee80211_tx_h_michael_mic_add,
	ieee80211_tx_h_rate_ctrl,
	ieee80211_tx_h_misc,                                         -- this
one already assume fragmetation
	ieee80211_tx_h_fragment,
	/* handlers after fragment must be aware of tx info fragmentation! */
	ieee80211_tx_h_encrypt,
	ieee80211_tx_h_stats,
	NULL
};


static ieee80211_tx_result
ieee80211_tx_h_misc(struct ieee80211_tx_data *tx)
{


          /* Setup duration field for the first fragment of the frame. Duration
	 * for remaining fragments will be updated when they are being sent
	 * to low-level driver in ieee80211_tx(). */
	dur = ieee80211_duration(tx, is_multicast_ether_addr(hdr->addr1),
				 (tx->flags & IEEE80211_TX_FRAGMENTED) ?
				 tx->extra_frag[0]->len : 0);                                 --
NULL pointer
