getting Software Brige IRQ CPU assign

I have Audience access point.

After restart wlan_ahb or wlan_pci irqs sometimes overlaps with software brige irq CPU (using same CPU), which leads to huge wifi performance degradation (up to 50%).

Is there a way, to look up current bridge IRQ Cpu assign? So I can automatically adjust wlan_ahb and wlan_pci irqs on different CPU, if these irq has same CPU as Brige one.
