From 38b922c9122789ce7f5dcb39a8f6bcaee10aa1cd Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Fri, 9 Sep 2022 14:38:00 +0300 Subject: [PATCH] net: enetc: expose some standardized ethtool counters Structure the code in such a way that it can be reused later for the pMAC statistics, by just changing the "mac" argument to 1. Usage: ethtool --include-statistics --show-pause eno2 ethtool -S eno0 --groups eth-mac ethtool -S eno0 --groups eth-ctrl ethtool -S eno0 --groups rmon Signed-off-by: Vladimir Oltean Reviewed-by: Claudiu Manoil Signed-off-by: Jakub Kicinski --- .../ethernet/freescale/enetc/enetc_ethtool.c | 111 ++++++++++++++++++ 1 file changed, 111 insertions(+) diff --git a/drivers/net/ethernet/freescale/enetc/enetc_ethtool.c b/drivers/net/ethernet/freescale/enetc/enetc_ethtool.c index b07139c97355..c8369e3752b0 100644 --- a/drivers/net/ethernet/freescale/enetc/enetc_ethtool.c +++ b/drivers/net/ethernet/freescale/enetc/enetc_ethtool.c @@ -301,6 +301,113 @@ static void enetc_get_ethtool_stats(struct net_device *ndev, data[o++] = enetc_port_rd(hw, enetc_port_counters[i].reg);
