3. WCSWREL-370: oob irq request fail on i.MX93 9x9 qsb board
4. WSW-21756: WLAN Driver hang observed during WiFi connect/disconnect
5. WCSWREL-362: merge the L6.0.0 build errors fix patches
6. WSW-22054: STA CSA event is not propagated to cfg80211
7. WSW-21873: STA does not send probes after switching from DFS channel
8. WSW-21530: UDP Tx not able to send ARP when high bandwidth is used
9. WSW-21541: WFA Pre-Cert Channel switch test is failing
10. WSW-21072: AP stops sending CTS-to-Self in mcast Tx after issue mc_aggr_cfg
