 155/**
 156 * Tx Scheduler
 157 *
 158 * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs
 159 * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in
 160 * host DRAM.  It steers each frame's Tx command (which contains the frame
 161 * data) into one of up to 7 prioritized Tx DMA FIFO channels within the
 162 * device.  A queue maps to only one (selectable by driver) Tx DMA channel,
 163 * but one DMA channel may take input from several queues.
 164 *
 165 * Tx DMA FIFOs have dedicated purposes.
 166 *
 167 * For 5000 series and up, they are used differently
 168 * (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.c):
 169 *
 170 * 0 -- EDCA BK (background) frames, lowest priority
 171 * 1 -- EDCA BE (best effort) frames, normal priority
 172 * 2 -- EDCA VI (video) frames, higher priority
 173 * 3 -- EDCA VO (voice) and management frames, highest priority
 174 * 4 -- unused
 175 * 5 -- unused
 176 * 6 -- unused
 177 * 7 -- Commands
 178 *
 179 * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
 180 * In addition, driver can map the remaining queues to Tx DMA/FIFO
 181 * channels 0-3 to support 11n aggregation via EDCA DMA channels.
 182 *
 183 * The driver sets up each queue to work in one of two modes:
 184 *
 185 * 1)  Scheduler-Ack, in which the scheduler automatically supports a
 186 *     block-ack (BA) window of up to 64 TFDs.  In this mode, each queue
 187 *     contains TFDs for a unique combination of Recipient Address (RA)
 188 *     and Traffic Identifier (TID), that is, traffic of a given
 189 *     Quality-Of-Service (QOS) priority, destined for a single station.
 190 *
 191 *     In scheduler-ack mode, the scheduler keeps track of the Tx status of
 192 *     each frame within the BA window, including whether it's been transmitted,
 193 *     and whether it's been acknowledged by the receiving station.  The device
 194 *     automatically processes block-acks received from the receiving STA,
 195 *     and reschedules un-acked frames to be retransmitted (successful
 196 *     Tx completion may end up being out-of-order).
 197 *
 198 *     The driver must maintain the queue's Byte Count table in host DRAM
 199 *     for this mode.
 200 *     This mode does not support fragmentation.
 201 *
 202 * 2)  FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
 203 *     The device may automatically retry Tx, but will retry only one frame
 204 *     at a time, until receiving ACK from receiving station, or reaching
 205 *     retry limit and giving up.
 206 *
 207 *     The command queue (#4/#9) must use this mode!
 208 *     This mode does not require use of the Byte Count table in host DRAM.
 209 *
 210 * Driver controls scheduler operation via 3 means:
 211 * 1)  Scheduler registers
 212 * 2)  Shared scheduler data base in internal SRAM
 213 * 3)  Shared data in host DRAM
 214 *
 215 * Initialization:
 216 *
 217 * When loading, driver should allocate memory for:
 218 * 1)  16 TFD circular buffers, each with space for (typically) 256 TFDs.
 219 * 2)  16 Byte Count circular buffers in 16 KBytes contiguous memory
 220 *     (1024 bytes for each queue).
 221 *
 222 * After receiving "Alive" response from uCode, driver must initialize
 223 * the scheduler (especially for queue #4/#9, the command queue, otherwise
 224 * the driver can't issue commands!):
