4 phylink  title
10 phylink is a mechanism to support hot-pluggable networking modules
14 phylink supports conventional phylib-based setups, fixed link setups
20 phylink has several modes of operation, which depend on the firmware

73 phylib to the sfp/phylink support.  Please send patches to improve

179    Manipulation of the PHY's supported/advertised happens within phylink
187    anymore; that is because in the phylink model, the PHY can be
238 	struct phylink *phylink;
242 	phylink = phylink_create(&priv->phylink_config, node, phy_mode, &phylink_ops);
243 	if (IS_ERR(phylink)) {
244 		err = PTR_ERR(phylink);
248 	priv->phylink = phylink;
250    and arrange to destroy the phylink in the probe failure path as
255 	phylink_destroy(priv->phylink);
258     phylink, via:
262 	phylink_mac_change(priv->phylink, link_is_up);
273    as these will interfere with phylink's tracking of the link state,
274    and cause phylink to omit calls via the :c:func:`mac_link_up` and
