Introduce support for standard MII ioctl operations in the LAN865x Ethernet driver by implementing the .ndo_eth_ioctl callback. This allows PHY-related ioctl commands to be handled via phy_do_ioctl_running() and enables support for ethtool and other user-space tools that rely on ioctl interface to perform PHY register access using commands like SIOCGMIIREG and SIOCSMIIREG. This feature enables improved diagnostics and PHY configuration capabilities from userspace. Signed-off-by: Parthiban Veerasooran --- v2: - Replaced custom lan865x_eth_ioctl() with direct use of phy_do_ioctl_running() to avoid code duplication. - Updated commit message to reflect the new change. --- drivers/net/ethernet/microchip/lan865x/lan865x.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/net/ethernet/microchip/lan865x/lan865x.c b/drivers/net/ethernet/microchip/lan865x/lan865x.c index 84c41f193561..f7cb685b1562 100644 --- a/drivers/net/ethernet/microchip/lan865x/lan865x.c +++ b/drivers/net/ethernet/microchip/lan865x/lan865x.c @@ -326,6 +326,7 @@ static const struct net_device_ops lan865x_netdev_ops = { .ndo_start_xmit = lan865x_send_packet, .ndo_set_rx_mode = lan865x_set_multicast_list, .ndo_set_mac_address = lan865x_set_mac_address, + .ndo_eth_ioctl = phy_do_ioctl_running, }; static int lan865x_probe(struct spi_device *spi) base-commit: d4854be4ec21dad23907c0fbc3389c3a394ebf67 -- 2.34.1
