By changing the CSU settings, you only prohibited bus accesses from the
normal world to that device. Nevertheless the Linux OS in the normal
world still tries to access the network card - that is why you
experienced the data abort. You have to disable the FEC access by
disabling that card in your Linux configuration.

Apart from that, AFAIK there is no FEC driver for Genode existent until now.
