Subject: [PATCH 2/3] net: ibm: emac: replace custom PHY_MODE_* macros
|
|
|
|
The ibm_emac driver predates the shared PHY_INTERFACE_MODE_
|
|
enums provided by include/linux/phy.h by a few years.
|
|
|
|
And while the driver has been retrofitted to use the PHYLIB,
|
|
the old definitions have stuck around to this day.
