Specifically, SFP needs to: - -1. set the negotiation mode between SGMII and 1000base-X -2. attach and detach the module PHY -3. prevent the link coming up when errors are reported - -In the absence of a PHY, we also need to set the ethtool port type -according to the module plugged in. - -Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> -Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> ---- - drivers/net/phy/phylink.c | 82 +++++++++++++++++++++++++++++++++++++++++++++++ - include/linux/phylink.h | 6 ++++ - 2 files changed, 88 insertions(+) - ---- a/drivers/net/phy/phylink.c -+++ b/drivers/net/phy/phylink.c -@@ -11,6 +11,7 @@ - #include <linux/ethtool.h> - #include <linux/export.h> - #include <linux/gpio/consumer.h> -+#include <linux/list.h> - #include <linux/netdevice.h> - #include <linux/of.h> - #include <linux/of_mdio.h> -@@ -29,11 +30,16 @@ - (ADVERTISED_TP | ADVERTISED_MII | ADVERTISED_FIBRE | \ - ADVERTISED_BNC | ADVERTISED_AUI | ADVERTISED_Backplane) - -+static LIST_HEAD(phylinks); -+static DEFINE_MUTEX(phylink_mutex); -+ - enum { - PHYLINK_DISABLE_STOPPED, -+ PHYLINK_DISABLE_LINK, - }; - - struct phylink { -+ struct list_head node; - struct net_device *netdev; - const struct phylink_mac_ops *ops; - struct mutex config_mutex; -@@ -341,12 +347,20 @@ struct phylink *phylink_create(struct ne - return ERR_PTR(ret); - } - -+ mutex_lock(&phylink_mutex); -+ list_add_tail(&pl->node, &phylinks); -+ mutex_unlock(&phylink_mutex); -+ - return pl; - } - EXPORT_SYMBOL_GPL(phylink_create); - - void phylink_destroy(struct phylink *pl) - { -+ mutex_lock(&phylink_mutex); -+ list_del(&pl->node); -+ mutex_unlock(&phylink_mutex); -+ - cancel_work_sync(&pl->resolve); - kfree(pl); - } -@@ -813,4 +827,72 @@ int phylink_mii_ioctl(struct phylink *pl - } - EXPORT_SYMBOL_GPL(phylink_mii_ioctl); - -+ -+ -+void phylink_disable(struct phylink *pl) -+{ -+ set_bit(PHYLINK_DISABLE_LINK, &pl->phylink_disable_state); -+ flush_work(&pl->resolve); -+ -+ netif_carrier_off(pl->netdev); -+} -+EXPORT_SYMBOL_GPL(phylink_disable); -+ -+void phylink_enable(struct phylink *pl) -+{ -+ clear_bit(PHYLINK_DISABLE_LINK, &pl->phylink_disable_state); -+ phylink_run_resolve(pl); -+} -+EXPORT_SYMBOL_GPL(phylink_enable); -+ -+void phylink_set_link_port(struct phylink *pl, u32 support, u8 port) -+{ -+ WARN_ON(support & ~SUPPORTED_INTERFACES); -+ -+ mutex_lock(&pl->config_mutex); -+ pl->link_port_support = support; -+ pl->link_port = port; -+ mutex_unlock(&pl->config_mutex); -+} -+EXPORT_SYMBOL_GPL(phylink_set_link_port); -+ -+int phylink_set_link_an_mode(struct phylink *pl, unsigned int mode) -+{ -+ int ret = 0; -+ -+ mutex_lock(&pl->config_mutex); -+ if (pl->link_an_mode != mode) { -+ ret = phylink_get_support(pl, mode); -+ if (ret == 0) { -+ if (!test_bit(PHYLINK_DISABLE_STOPPED, -+ &pl->phylink_disable_state)) -+ phylink_mac_config(pl, &pl->link_config); -+ -+ netdev_info(pl->netdev, "switched to %s link mode\n", -+ phylink_an_mode_str(mode)); -+ } -+ } -+ mutex_unlock(&pl->config_mutex); -+ -+ return ret; -+} -+EXPORT_SYMBOL_GPL(phylink_set_link_an_mode); -+ -+struct phylink *phylink_lookup_by_netdev(struct net_device *ndev) -+{ -+ struct phylink *pl, *found = NULL; -+ -+ mutex_lock(&phylink_mutex); -+ list_for_each_entry(pl, &phylinks, node) -+ if (pl->netdev == ndev) { -+ found = pl; -+ break; -+ } -+ -+ mutex_unlock(&phylink_mutex); -+ -+ return found; -+} -+EXPORT_SYMBOL_GPL(phylink_lookup_by_netdev); -+ - MODULE_LICENSE("GPL"); ---- a/include/linux/phylink.h -+++ b/include/linux/phylink.h -@@ -67,4 +67,10 @@ int phylink_ethtool_get_settings(struct - int phylink_ethtool_set_settings(struct phylink *, struct ethtool_cmd *); - int phylink_mii_ioctl(struct phylink *, struct ifreq *, int); - -+void phylink_set_link_port(struct phylink *pl, u32 support, u8 port); -+int phylink_set_link_an_mode(struct phylink *pl, unsigned int mode); -+void phylink_disable(struct phylink *pl); -+void phylink_enable(struct phylink *pl); -+struct phylink *phylink_lookup_by_netdev(struct net_device *ndev); -+ - #endif |
