net: dsa: netc: add support for ethtool private statisticsImplement the ethtool private statistics interface to expose additionalport-level and MAC-level counters that are not covered by the standardIEEE 802.3 statistics. The pMAC counters are only reported when the portsupports Frame Preemption (802.1Qbu/802.3br).Note that although rtnl_link_stats64 provides some standard statisticssuch as rx octets, rx frame errors, rx dropped packets, and tx packets,these are overall port statistics. The NETC switch supports preemptionon each port, and each port has two MACs (eMAC and pMAC). The driverprivate statistics are used to obtain statistics for each MAC, allowingusers to perform analysis and debugging.Signed-off-by: Wei Fang Link: https://patch.msgid.link/20260518082506.1318236-16-wei.fang@nxp.comSigned-off-by: Paolo Abeni List of files: /linux/drivers/net/dsa/netc/netc_ethtool.c

net: dsa: netc: add support for the standardized countersEach user port of the NETC switch supports 802.3 basic and mandatorymanaged objects statistic counters and IETF Management InformationDatabase (MIB) package (RFC2665) and Remote Network Monitoring (RMON)counters. And all of these counters are 64-bit registers. In addition,some user ports support preemption, so these ports have two MACs, MAC0 is the express MAC (eMAC), MAC 1 is the preemptible MAC (pMAC). Sofor ports that support preemption, the statistics are the sum of thepMAC and eMAC statistics.Note that the current switch driver does not support preemption, allframes are sent and received via the eMAC by default. The statisticsread from the pMAC should be zero.Signed-off-by: Wei Fang Link: https://patch.msgid.link/20260518082506.1318236-15-wei.fang@nxp.comSigned-off-by: Paolo Abeni List of files: /linux/drivers/net/dsa/netc/netc_ethtool.c
