Thanks, I guess we can remove these if building with DEBUG=virtio-net:2 was intentional and it interferes with other output. But then again, if you build for example with DEBUG=tcp:2, you'll see a debug message for each transmitted or received packet also. > cheers, > Gerd > _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
