Network driver issues when upgrading to Mojave

[Markus Fischer]

Dear list-members,

we have a network card called Myri-10G for which we have developed our
own network driver. In a Mac Pro system (from 2013) we have the NIC
working fine - under High Sierra - when the NIC is connected via
Thunderbolt. (All Thunderbolt2 setup).

Now, we are noticing that when running the very same system with Mojave
that the NIC does not receive correct data. While TX works, RX does not.

Upon getting a packet (RX), we see in dmesg:

vtd[5] fault: device 236:0:0 reason 0x5 W:0x0

Anyone has some information he might share related to this? e.g does it
make sense to "disable vtd", we see web pages mentioning setting
dart=0x0 but we are not able to set this under Mojave.

thanks,

Kind regards,
Markus
