Subject: [net 1/5] ixgbe: Return error when getting PHY address if PHY access is not supported
From: Mark D Rustad <mark.d.rustad@...el.com>
In cases where PHY register access is not supported, don't mislead
a caller into thinking that it is supported by returning a PHY
address. Instead, return -EOPNOTSUPP when PHY access is not
supported.
