By design, PTP timestamping with a DSA switch does not need any special
handling in the driver for the host port it is attached to. However, when the
host port also supports PTP timestamping, DSA will take care of intercepting
-the ``.ndo_do_ioctl`` calls towards the host port, and block attempts to enable
+the ``.ndo_eth_ioctl`` calls towards the host port, and block attempts to enable
hardware timestamping on it. This is because the SO_TIMESTAMPING API does not
allow the delivery of multiple hardware timestamps for the same packet, so
anybody else except for the DSA switch port must be prevented from doing so.
driver. Therefore, as opposed to DSA switches, modifications need to be done
to each individual MAC driver for PHY timestamping support. This entails:
-- Checking, in ``.ndo_do_ioctl``, whether ``phy_has_hwtstamp(netdev->phydev)``
+- Checking, in ``.ndo_eth_ioctl``, whether ``phy_has_hwtstamp(netdev->phydev)``
is true or not. If it is, then the MAC driver should not process this request
but instead pass it on to the PHY using ``phy_mii_ioctl()``.

1. "TX": checks whether PTP timestamping has been previously enabled through
