10 phylink is a mechanism to support hot-pluggable networking modules
11 directly connected to a MAC without needing to re-initialise the
12 adapter on hot-plug events.
14 phylink supports conventional phylib-based setups, fixed link setups
23 1. PHY mode
25 In PHY mode, we use phylib to read the current link settings from
26 the PHY, and pass them to the MAC driver. We expect the MAC driver
32 Fixed mode is the same as PHY mode as far as the MAC driver is
