Hi Levente ,

Thanks for the note. I suppose there is no "one-size-fit-all" solution
to the issue. The original reason why r8169 was blacklisted was that,
with the kmod-r8125 in RHEL 10, it still used the r8169 driver. Of
course, when you have 2 NICs, the situation is not as simple as
disabling one driver or the other.

We'd like to get a good and reasonable solution but in the mean time,
we could revert the change if that works as a temporary fix.
