Subject: [PATCH v6 2/9] raw/cnxk_rvu_lf: support NPA/SSO pffunc get
Date: Mon, 28 Oct 2024 16:31:08 +0530 [thread overview]
Message-ID: <20241028110115.1070655-3-gakhil@marvell.com> (raw)
In-Reply-To: <20241028110115.1070655-1-gakhil@marvell.com>
Added rte_pmd_rvu_lf_npa_pf_func_get and
rte_pmd_rvu_lf_sso_pf_func_get APIs to get NPA and
SSO pffunc for the application/external driver use.

+Get NPA and SSO PF FUNC
