## Overview

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

net: ethernet: aeroflex: move setting of netops to fix crash

greth_of_probe() calls greth_mdio_init(), 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").

## Affected

- `Linux >= ded86da4bbb78cad74cecc368fee3ae3a296e2ca < 5293e376e9d6cdb945db11f71821bb57d415631d`
- `Linux >= ded86da4bbb78cad74cecc368fee3ae3a296e2ca < d71483f0716e7ae98578817bfdc8a5b822d250f8`
- `Linux 7.2`
