I am able to compile the kernel with the patch you posted and now I am getting the following errors:

I can connect to the network with the card, but it disconnects itself from time to time from the router and loses connection spamming the following messages:

I found some messages saying that using kernel parameter iommu=soft helps here but this is not the case.

In case you update the patch I am willing to test it. Thanks in advance.
