Thx, I remember a few years back I changed NIC properties and I got max samples to 1996. No changes in uhd calls. When I upgraded and reinstalled the NIC driver, I lost those settings, and now I am getting max samples 396:( I remember changing things like coalescense, but I don't remember what and by how much. Back then I got the advice from here. So, if anyone remembers... For now I will change my MTU and pass the sizes to the device...
