do this correctly (yet).
Just as an example, in rt2x00 we just have to set one bit in the tx
descriptor to
force the hw to send out a 1-stream RTS to wake up the peer, from
rt2x00queue.c:
/*
* MIMO PS should be set to 1 for
STA's using dynamic SM PS
* when using more then one tx stream
(>MCS7).
*/
if (sta && txdesc->u.ht.mcs > 7 &&
sta->smps_mode ==
IEEE80211_SMPS_DYNAMIC)
__set_bit(ENTRY_TXD_HT_MIMO_PS, &txdesc->flags);
HTH,
Helmut
