net: dpaa2-mac: extend APIs related to statistics
Extend the dpmac_counter_id enum with the newly added counters which can be interrogated through the MC firmware. Also add the dpmac_get_statistics() API which can be used to retrieve multiple MAC counters through a single firmware command. Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com> Link: https://patch.msgid.link/20260323115039.3932600-2-ioana.ciornei@nxp.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
