Commit 6570bc79c0df ("net: core: use listified Rx for GRO_NORMAL in
napi_gro_receive()") has applied batched GRO_NORMAL packets processing
to all napi_gro_receive() users, including mac80211-based drivers.
However, this change has led to a regression in iwlwifi driver [1][2] as
it is required for NAPI users to call napi_complete_done() or
napi_complete() and the end of every polling iteration, whilst iwlwifi
doesn't use NAPI scheduling at all and just calls napi_gro_flush().
In that particular case, packets which have not been already flushed
from napi->rx_list stall in it until at least next Rx cycle.
Fix this by adding a manual flushing of the list to iwlwifi driver right
before napi_gro_flush() call to mimic napi_complete() logics.
I prefer to open-code gro_normal_list() rather than exporting it for 2
reasons:
* to prevent from using it and napi_gro_flush() in any new drivers,
as it is the *really* bad way to use NAPI that should be avoided;
* to keep gro_normal_list() static and don't lose any CC optimizations.
I also don't add the "Fixes:" tag as the mentioned commit was only a
trigger that only exposed an improper usage of NAPI in this particular
driver.

When virt_wifi interface is created, virt_wifi_newlink() is called and
it calls register_netdevice().
if register_netdevice() fails, it internally would call
->priv_destructor(), which is virt_wifi_net_device_destructor() and
it frees netdev. but virt_wifi_newlink() still use netdev.
So, use-after-free would occur in virt_wifi_newlink().
Test commands:
ip link add dummy0 type dummy
modprobe bonding
ip link add bonding_masters link dummy0 type virt_wifi
Splat looks like:

This reverts commit 34b0e9b767bfa09ae233ca0d6ceb299bf2e24600.
Since commit 7bd0650be63c ("mt76: dma: fix buffer unmap with non-linear skbs")
is no longer necessary to disable HW encryption for MT7630E.
Disabling HW encryption helped previously because somehow fragmented
skb's are not created if mac80211 encrypt frames, so buffer unmap bug
of non-linear skbs was not triggered. Now since this bug is properly
fixed by commit 7bd0650be63c ("mt76: dma: fix buffer unmap with
non-linear skbs") , we can enable HW encryption back.

mt76x0e driver only supports MAC addresses from
calibration data eeprom. Many routers however do not
have a valid stock address set in this field.
This patch makes it possible to take a MAC address
from OF (e.g. from mtd).

A rcu read locked section is not allowed to sleep, and the rcu lock here
isn't actually necessary, because we're holding dev->mutex.

With the devm API, the unregister happens after the device cleanup is done,
after which the struct mt76_dev which contains the led_cdev has already been
freed. This leads to a use-after-free bug that can crash the system.
