| |
From: Andrew Lunn <andrew@lunn.ch>
Some PHYs provide invalid IDs in C22 space. If C45 is supported on the bus an attempt can be made to get the IDs from the C45 space. Decide on this based on the presence of the C45 read method in the bus structure. This will allow the unreliable probe_capabilities to be removed.
