this is hard to read in the first place.
Maybe using switch() here is better to read (untested example below).


	switch(priv->ieee80211->current_network.mode) {

	case IEEE_A:
	case IEEE_N_5G:
	 tx_rate = 60;
         break;
        IEEE_N_24G:
	     if ( !priv->ieee80211->pHTInfo->bCurSuppCCK )
		tx_rate = 60;
             // fall truh

        default:
		tx_rate = 10;

	}	

	if (txrate == 60 )
	     DMESG("send beacon frame  tx rate is 6Mbpm\n");
	else if (txrate == 10 )
	     DMESG("send beacon frame  tx rate is 1Mbpm\n");
