APIs ``rte_pmd_rvu_lf_npa_pf_func_get()`` and
``rte_pmd_rvu_lf_sso_pf_func_get()``
can be used to get the cnxk NPA PF func and SSO PF func which application
can use for NPA/SSO specific configuration.

+Register or remove interrupt handler
+------------------------------------
+
+Application can register interrupt handlers using
``rte_pmd_rvu_lf_irq_register()``
+or remove interrupt handler using ``rte_pmd_rvu_lf_irq_unregister()``.
+The irq numbers for which the interrupts are registered is negotiated
separately
+and is not in scope of the driver.
