 Hi:
   ALL.
   I want to do some research about link adpatation via snr.I have one
 problem to look for answer here. In this scenario, A and B are two nodes
 in one same IEEE 802.11 wlan. when node A send one packet to node B,how
 can I make node A get the snr value of the packet when the packet reachs
 node B.
   struct ath_tx_status {
         u_int16_t       ts_seqnum;      /* h/w assigned sequence number */
         u_int16_t       ts_tstamp;      /* h/w assigned timestamp */
         u_int8_t        ts_status;      /* frame status, 0 => xmit ok */
         u_int8_t        ts_rate;        /* h/w transmit rate index */
 #define HAL_TXSTAT_ALTRATE      0x80    /* alternate xmit rate used */
         int8_t          ts_rssi;        /* tx ack RSSI */
         u_int8_t        ts_shortretry;  /* # short retries */
         u_int8_t        ts_longretry;   /* # long retries */
         u_int8_t        ts_virtcol;     /* virtual collision count */
         u_int8_t        ts_antenna;     /* antenna information */
 };
   In this structure, there is one memeber named ts_rssi, what is it for?
 who can explain it to me detailedly,not only the comment tx ack RSSI.
   Thanks for your help very much!
