Subject: [PATCH 1/3] net: ibm: emac: replace custom rgmii_mode_name with
phy_modes
The common phylib defines the same names (in lower-case).
Since rgmii_mode_name() is used only in one place and
for a "notice-level" printk, I think it can be replaced.

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.

Subject: [PATCH 3/3] net: ibm: emac: support RGMII-[RX|TX]ID phymode
The RGMII spec allows compliance for devices that implement an internal
delay on TXC and/or RXC inside the transmitter. This patch adds the
necessary RGMII_[RX|TX]ID mode code to handle such PHYs with the
emac driver.
Signed-off-by: Christian Lamparter <chunkeey@gmail.com>

v3: - replace PHY_MODE_* with PHY_INTERFACE_MODE_*
- replace rgmii_mode_name() with phy_modes[]
v2: - utilize phy_interface_mode_is_rgmii()
