I understand the need for the "cards" parameter, but...
Is not there another way to solve this issue ? I do not know,
something in /proc or /sys to tell Linux to not load this driver for
that card? I suppose if we tell Linux to not use its driver for some
cards, then later loading the rtnet driver will be used for these
cards? Adding the cards parameter means that the rtnet drivers
diverge from mainline drivers, and so imply a maintenance cost. On
the other hand, maybe that is a cheaper one than trying and solving
the issue globally.
