wlcore: improved Tx scheduling algorithm
Prioritize EDCA by choosing the AC before anything else. Use the fast/slow link bitmap in FW to improve the scheduling algorithm for the multi-link scenario. Set packet thresholds to determine if a given link is high or low priority according to its speed. A slow link will be given high priority if the amount of packets queued for it in the FW is lower than the slow-threshold. Similarly, a fast link will be given high priority if the number of its packets queued in FW is smaller than the high-threshold. The improved algorithm: 1. Choose optimal AC according to FW utilization 2. Traversing the VIFs in a round-robin fashion, try to choose a high priority link. Links are traversed in a round-robin fashion inside a VIF. 3. If no high priority links are found, choose the first non-empty (low priority) link found in the round robin.
