[dpdk-dev] [PATCH 29/29] net/sfc/base: add APIs for PTP privilege configuration

[Andrew Rybchenko <arybchenko@solarflare.com>]

From: Gautam Dawar <gdawar@solarflare.com>

Implement the efx_proxy_auth_privilege_mask_get() to get a function's
privilege mask and efx_proxy_auth_privilege_modify() to add/remove
privileges for a function specified by PF and VF index.
