Intel e1000e driver bug on stable (6.9.x)

Hi,

I noticed that the NIC started to fail on a couple of notebooks [0]
[1] after upgrading to 6.9.1.

I tracked down the problem to commit 861e8086029e ("e1000e: move force
SMBUS from enable ulp function to avoid PHY loss issue", 2024-03-03),
included in all 6.9.x releases.

The fix is in commit bfd546a552e1 ("e1000e: move force SMBUS near
the end of enable_ulp function", 2024-05-28) from mainline.

The NIC fails right after boot on both systems I tried; I mention
because the description is a bit unclear about that on the fix, maybe
other systems are affected differently.

Best regards.
