In mesh_mpm_plink_estab we had:

       /* TODO
      changed |= mesh_set_ht_op_mode(cand->conf->mesh);
       */

We removed this as part of pushing mesh support upstream, because of a comment from Thomas:

..but we've already have HT support implemented... maybe not completely? Perhaps the HT protection mode is not being setup correctly, according to the HT IEs.

Other references to this follow:
In mesh_mpm_fsm:

         case PLINK_ESTAB:                                                           
         switch (event) {                                                        
         case CLS_ACPT:                                                          
             wpa_mesh_set_plink_state(wpa_s, sta, PLINK_HOLDING);                
             reason = WLAN_REASON_MESH_CLOSE_RCVD;                               

            eloop_register_timeout(dot11MeshHoldingTimeout, 0, plink_timer, wpa_s, sta);
            /* TODO                                                             
            changed |= mesh_set_ht_op_mode(cand->conf->mesh);                   
            */                                                                  
            sta->mpm_close_reason = reason; 

and later in mesh_mpm_fsm:

    default:                                                                    
        wpa_msg(wpa_s, MSG_INFO, "Unsupported MPM event %s for state %s",       
                        mplevent[event], mplstate[sta->plink_state]);               
        break;                                                                  
    }                                                                           
    /* TODO                                                                         
    if (changed)                                                                
        meshd_set_mesh_conf(cand->conf->mesh, changed);
