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> - -- rework phylink_set_link_*(), combining into a single function. ---- - ---- 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; -@@ -375,12 +381,20 @@ struct phylink *phylink_create(struct ne - phylink_init_advert(pl, pl->link_an_mode, pl->supported, - pl->link_config.advertising); - -+ 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); - } -@@ -900,4 +914,93 @@ 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); -+ -+int phylink_set_link(struct phylink *pl, unsigned int mode, u8 port, -+ const unsigned long *support) -+{ -+ __ETHTOOL_DECLARE_LINK_MODE_MASK(mask); -+ int ret = 0; -+ -+ netdev_dbg(pl->netdev, "requesting link mode %s with support %*pb\n", -+ phylink_an_mode_str(mode), -+ __ETHTOOL_LINK_MODE_MASK_NBITS, support); -+ -+ if (mode == MLO_AN_FIXED) -+ return -EINVAL; -+ -+ linkmode_copy(mask, support); -+ -+ /* Ignore errors if we're expecting a PHY to attach later */ -+ ret = phylink_validate_support(pl, mode, mask); -+ if (ret && mode != MLO_AN_PHY) -+ return ret; -+ -+ mutex_lock(&pl->config_mutex); -+ if (mode == MLO_AN_8023Z && pl->phydev) { -+ ret = -EINVAL; -+ } else { -+ bool changed = !bitmap_equal(pl->supported, mask, -+ __ETHTOOL_LINK_MODE_MASK_NBITS); -+ if (changed) { -+ linkmode_copy(pl->supported, mask); -+ -+ phylink_init_advert(pl, mode, mask, -+ pl->link_config.advertising); -+ } -+ -+ if (pl->link_an_mode != mode) { -+ pl->link_an_mode = mode; -+ -+ changed = true; -+ -+ netdev_info(pl->netdev, "switched to %s link mode\n", -+ phylink_an_mode_str(mode)); -+ } -+ -+ pl->link_port = port; -+ -+ if (changed && !test_bit(PHYLINK_DISABLE_STOPPED, -+ &pl->phylink_disable_state)) -+ phylink_mac_config(pl, &pl->link_config); -+ } -+ mutex_unlock(&pl->config_mutex); -+ -+ return ret; -+} -+EXPORT_SYMBOL_GPL(phylink_set_link); -+ -+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 -@@ -88,6 +88,12 @@ int phylink_ethtool_ksettings_set(struct - const struct ethtool_link_ksettings *); - int phylink_mii_ioctl(struct phylink *, struct ifreq *, int); - -+int phylink_set_link(struct phylink *pl, unsigned int mode, u8 port, -+ const unsigned long *support); -+void phylink_disable(struct phylink *pl); -+void phylink_enable(struct phylink *pl); -+struct phylink *phylink_lookup_by_netdev(struct net_device *ndev); -+ - #define phylink_zero(bm) \ - bitmap_zero(bm, __ETHTOOL_LINK_MODE_MASK_NBITS) - #define __phylink_do_bit(op, bm, mode) \ |
