| D | fixed-link.txt | 1 Fixed link Device Tree binding
2 ------------------------------
4 Some Ethernet MACs have a "fixed link", and are not connected to a
5 normal MDIO-managed PHY device. For those situations, a Device Tree
6 binding allows to describe a "fixed link".
8 Such a fixed link situation is described by creating a 'fixed-link'
9 sub-node of the Ethernet MAC device node, with the following
12 * 'speed' (integer, mandatory), to indicate the link speed. Accepted
14 * 'full-duplex' (boolean, optional), to indicate that full duplex is
18 * 'asym-pause' (boolean, optional), to indicate that asym_pause should
