## Overview

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

net: hisilicon: hisi_femac: Move setting of netops to fix crash

hisi_femac_drv_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.

  phy_link_topo_add_phy from phy_attach_direct+0xec/0x37c
  of_phy_get_and_connect from hisi_femac_drv_probe+0x1f4/0x558
  Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

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