In fact technically IEEE-802.11 2007 section 11.7 states "STAs are not allowed to transmit frames directly to other STAs in a BSS and should always rely on the AP for the delivery of the frames", with the exception being using DLS direct links for QoS STAs. This would prevent the STAs from going into PS mode for as long duration of the stream. If the AP does not support this it would just set the result code for DLS requests to "Not allowed in the BSS". It does not seem the standard has a way for an AP to teardown an existing DLS links though (at no reason code for it), so I guess if we ever support DLS we won't be able to enable this option if a direct links is already established.
