231 Note for SP ACCURATE Mechanism:
232 1. When traffic is busy for the PS station
233 Statistics FIFO counter maybe overflow before we read it, so UAPSD
234 counting mechanism will not accurately.
235
236 Solution:
237 We need to avoid the worse case so we suggest a maximum interval for
238 a SP that the interval between last frame from QAP and data frame from
239 QSTA is larger than UAPSD_EPT_SP_INT.
240
241 2. When traffic use CCK/1Mbps from QAP
242 Statistics FIFO will not count the packet. There are 2 cases:
243 (1) We force to downgrage ARP response & DHCP packet to 1Mbps;
244 (2) After rate switch mechanism, tx rate is fixed to 1Mbps.
245
246 Solution:
247 Use old DMA UAPSD mechanism.
248
249 3. When part of AC uses legacy PS mode
250 Statistics count will inclue packet statistics for legacy PS packets
251 so we can not know which one is UAPSD, which one is legacy.
252
253 Solution:
254 Cound the legacy PS packet.
255
256 4. Check FIFO statistics count in Rx Done function
257 We can not to check TX FIFO statistics count in Rx Done function or
258 the real packet tx/rx sequence will be disarranged.
259
260 Solution:
261 Suspend SP handle before rx done and resume SP handle after rx done.
