dev_irq_affinity
================

.. code-block:: text

   Set the IRQ affinity for a network device to pin interrupts to specific CPU cores.

   Kills irqbalance first, then uses set_irq_affinity_cpulist.sh if available,
   otherwise falls back to a built-in script (based on Intel/Robert Olsson).
   The OFFSET variable allows shifting the CPU core assignment.

   Variables:
     N      - Number of CPU cores to use (if empty, uses all available)
     NIC    - NIC index to configure (default: 0)
     OFFSET - First CPU core index to start binding from (default: 0)

   Usage:
     %import@dut dev_irq_affinity N=4 NIC=0 OFFSET=0
