44 DISASSOCIATION_REASON_CODE_PSP_TX_PKT_BUFFER_EXCEEDED Symbol defined (non-802.11
standard) code. The switch has
exceeded its time limit in
attempting to deliver buffered PSP
frames to the mobile unit without
receiving a single 802.11 PS poll or
NULL data frame. The switch
begins the timer when it sets the
mobile unit’s bit in the TIM section
of the 802.11 beacon frame for the
BSS. The time limit is at least 15
seconds. The mobile unit is
probably gone (or may be faulty).
