## Overview

In the Linux kernel, the following vulnerability has been resolved:

net: mv643xx: move setting of netops to fix crash

mv643xx_eth_probe() connects the PHY before dev->netdev_ops is
assigned. phy_attach_direct() -> phy_link_topo_add_phy() reads
dev->netdev_ops through netdev_need_ops_lock() since the commit in
question, so probing crashes with a NULL pointer dereference when
CONFIG_NET_SHAPER is enabled.

Assign netdev_ops before the PHY attach, as was done for emac in commit
7c9f391ec89c ("net: emac: move setting of netops to fix crash").
