Re: [Patch] mac80211: add rts-cts for dynamic SMPS stations

[Vivekananda Holla <vivekanandah@posedge.com>]

Hi Johannes,

I ran checkpatch.pl script and found some trailing white spaces in the patch which i have now
corrected.
 
Also,i had initially placed my code in minstrel_ht_get_rate but saw that the minstrel code is being
changed.
hence, moved the code in to ieee80211_tx_h_rate_ctrl function.

there is a check in this function

        if (info->control.rates[i].flags & IEEE80211_TX_RC_MCS) {
            WARN_ON(info->control.rates[i].idx > 76);
            continue;
        }
 
I feel it would be okay to move  the code for dyn_smps within this loop as
this would solve the check for MCS rates.

however i am not sure whether all ht rates flag settings need to be handled within minstrel_ht?

        if (info->control.rates[i].flags & IEEE80211_TX_RC_MCS) {
            WARN_ON(info->control.rates[i].idx > 76);

+        if (dyn_smps) {
+            if ((info->control.rates[i].idx > 7) &&
+                (info->control.rates[i].idx != 32))
+                info->control.rates[i].flags |=
+                    IEEE80211_TX_RC_USE_RTS_CTS;    


            continue;
        }

awaiting your inputs

thanks and regards
Vivek
