From ef5eb9c5ce45deb4af0898778e2536fda80bc362 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Tue, 1 Aug 2023 17:28:18 +0300 Subject: net: fec: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set() The hardware timestamping through ndo_eth_ioctl() is going away. Convert the FEC driver to the new API before that can be removed. After removing the timestamping logic from fec_enet_ioctl(), the rest is equivalent to phy_do_ioctl_running().
