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

ice: Add netif_device_attach/detach into PF reset flow

Ethtool callbacks can be executed while reset is in progress and try to
access deleted resources, e.g. getting coalesce settings can result in a
NULL pointer dereference seen below.

Reproduction steps:
Once the driver is fully initialized, trigger reset:
# echo 1 > /sys/class/net/<interface>/device/reset
when reset is in progress try to get coalesce settings using ethtool:
# ethtool -c <interface>

Calling netif_device_detach() before reset makes the net core not call
the driver when ethtool command is issued, the attempt to execute an
ethtool command during reset will result in the following message:

netlink error: No such device

instead of NULL pointer dereference. Once reset is done and
ice_rebuild() is executing, the netif_device_attach() is called to allow
for ethtool operations to occur again in a safe manner.
