Continue to main subject , I bought new modem with PCIe mode for this modem 5G
I did some test (PCIe ) between MCUZONE and OpenWrt
MCUZONE PCIe
i'm getting 800mb/s to 900mb/s like USB Speeds (before)
Where The PCIe for OpenWrt
i'm getting 550 mb/s
So I started searching to know why ? I found CPU utilization ( when Its running for all CPUs 0,1,2 & 3) IRQ .......only CPU 0 is running and reaching up to 75% utilization where other CPUs 1,2 and 3 are almost sleeping (
low utilization) 
So I tried to let all CPUs run at same time on PCIe mode but no luck ... still system is assigning load to CPU 0 also when I activated IRQ package to disrepute load but no luck
Also with this
echo f > /sys/class/net/usb0/queues/rx-0/rps_cpus
only CPU 0 is running
I did one thing made a big different on speed and utilization
echo 2 > /proc/irq/116/smp_affinity
Where CPU 1 gave a good speeds

CPU 1 and 2 are giving a higher speeds
CPU 0 and 4 are giving a lower speeds
I appreciate answering on these questions 
How I can let the OpenWrt use all CPUs ? only CPU 0 will work .... echo f > /proc/irq/116/smp_affinity
root@OpenWrt:~# echo 3f > /sys/class/net/usb0/queues/rx-0/rps_cpus
ash: write error: Value too large for data type
root@OpenWrt:~# echo f > /sys/class/net/usb0/queues/rx-0/rps_cpus <<<---- (This only worked , where only CPU 0 will run )
How I can let OpenWrt use CPU 1 and 2 same time ?
echo 6 > /proc/irq/116/smp_affinity
I tried this echo and didn't work for dual cores (1 & 2) only core 1 was running and core 2 idle
When I tried with ChatGPT 4 ,each step with sharing results with GPT ... he/it felt there is something wrong with Kernel or Network Drivers
