Currently, the port info(speed, duplex and autoneg) is stored in hclge_mac and will be scheduled updated. Consider the case that reset was happened consecutively. During the first reset, the port info is configured with a temporary value cause the PHY is reset and looking for best link config. Second reset start and use pervious configuration which is not the user's. The specific process is as follows: +------+ +----+ +----+ | USER | | PF | | HW | +---+--+ +-+--+ +-+--+ | ethtool --reset | | +------------------->| reset command | | ethtool --reset +-------------------->| +------------------->| +---+ | +---+ | | | | |reset currently | | HW RESET | | |and wait to do | | | |<--+ | | | | send pervious cfg |<--+ | | (1000M FULL AN_ON) | | +-------------------->| | | read cfg(time task) | | | (10M HALF AN_OFF) +---+ | |<--------------------+ | cfg take effect | | reset command |<--+ | +-------------------->| | | +---+ | | send pervious cfg | | HW RESET | | (10M HALF AN_OFF) |<--+ | +-------------------->| | | read cfg(time task) | | | (10M HALF AN_OFF) +---+ | |<--------------------+ | cfg take effect | | | | | | read cfg(time task) |<--+ | | (10M HALF AN_OFF) | | |<--------------------+ | | | v v v To avoid aboved situation, this patch introduced req_speed, req_duplex, req_autoneg to store user's configuration and it only be used after hardware reset and to recover user's configuration Fixes: f5f2b3e4dcc0 ("net: hns3: add support for imp-controlled PHYs") Signed-off-by: Peiyang Wang Signed-off-by: Jijie Shao Reviewed-by: Przemek Kitszel Reviewed-by: Simon Horman --- .../ethernet/hisilicon/hns3/hns3pf/hclge_main.c | 15 +++++++++------ .../ethernet/hisilicon/hns3/hns3pf/hclge_main.h | 3 +++ 2 files changed, 12 insertions(+), 6 deletions(-) diff --git a/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.c b/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.c index ff6a2ed23ddb..8043f1795dc7 100644 --- a/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.c +++ b/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.c @@ -1537,6 +1537,9 @@ static int hclge_configure(struct hclge_dev *hdev) cfg.default_speed, ret); return ret; } + hdev->hw.mac.req_speed = hdev->hw.mac.speed; + hdev->hw.mac.req_autoneg = AUTONEG_ENABLE; + hdev->hw.mac.req_duplex = DUPLEX_FULL; hclge_parse_link_mode(hdev, cfg.speed_ability); @@ -3342,9 +3345,9 @@ hclge_set_phy_link_ksettings(struct hnae3_handle *handle, return ret; } - hdev->hw.mac.autoneg = cmd->base.autoneg; - hdev->hw.mac.speed = cmd->base.speed; - hdev->hw.mac.duplex = cmd->base.duplex; + hdev->hw.mac.req_autoneg = cmd->base.autoneg; + hdev->hw.mac.req_speed = cmd->base.speed; + hdev->hw.mac.req_duplex = cmd->base.duplex; linkmode_copy(hdev->hw.mac.advertising, cmd->link_modes.advertising); return 0; @@ -3377,9 +3380,9 @@ static int hclge_tp_port_init(struct hclge_dev *hdev) if (!hnae3_dev_phy_imp_supported(hdev)) return 0; - cmd.base.autoneg = hdev->hw.mac.autoneg; - cmd.base.speed = hdev->hw.mac.speed; - cmd.base.duplex = hdev->hw.mac.duplex; + cmd.base.autoneg = hdev->hw.mac.req_autoneg; + cmd.base.speed = hdev->hw.mac.req_speed; + cmd.base.duplex = hdev->hw.mac.req_duplex; linkmode_copy(cmd.link_modes.advertising, hdev->hw.mac.advertising); return hclge_set_phy_link_ksettings(&hdev->vport->nic, &cmd); diff --git a/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.h b/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.h index e821dd2f1528..e3c69be8256f 100644 --- a/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.h +++ b/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.h @@ -279,11 +279,14 @@ struct hclge_mac { u8 media_type; /* port media type, e.g. fibre/copper/backplane */ u8 mac_addr[ETH_ALEN]; u8 autoneg; + u8 req_autoneg; u8 duplex; + u8 req_duplex; u8 support_autoneg; u8 speed_type; /* 0: sfp speed, 1: active speed */ u8 lane_num; u32 speed; + u32 req_speed; u32 max_speed; u32 speed_ability; /* speed ability supported by current media */ u32 module_type; /* sub media type, e.g. kr/cr/sr/lr */
