## Overview

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

net: au1000: move setting of netops to fix crash

au1000_probe() calls au1000_mii_probe(), which 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").
