   Next time when the kernel thread "sofirqd" is scheduled , it executes
   the RX softirq. As the version you are using is a non-preemptive kernel,
   the control paths are all non-deterministic. So the longer interrupt
   processing

Absolutely wrong, softirqs run at the return from any hardware
interrupt trap as long as we are not already inside of a hw
interrupt.

softirqs runs to handle softirqs in process context when softirqs are
"overloaded".
