default:
The custom swap function used in octeontx driver do not perform any special operations and can be replaced with the built-in swap function of sort. This change not only reduces code size but also improves efficiency, especially in scenarios where CONFIG_RETPOLINE is enabled, as it makes indirect function calls more expensive. By using the built-in swap, we avoid these costly indirect function calls, leading to better performance.
