Hi Sven
I can confirm great stability improvement after your patch
"lan743x: boost performance on cpu archs w/o dma cache snooping".
Please note, that test_ber opens raw sockets as
s = socket(AF_PACKET, SOCK_RAW, ETH_P_ALL)
and resulting 'average speed' is a average egress speed.
Test machine is I

v4:
Sven Van Asbruck noticed that the patch was being applied cleanly to the 5.9
branch, so the tag “Fixes” was added as Jakub suggested.

The reason for the fix is when the device is down netdev->phydev will be NULL
and there is no checking for this situation. So 'ethtool ethN' leads to kernel
panic.
$ sudo ethtool eth7

This is just a minor fix which prevents a kernel NULL pointer
dereference when using phy-less lan743x.
