Timur, I strongly suspect that the NMI watchdog softlockups caused by mlx5_core dma mapping is the root cause of why qcom_emac driver is unable to get a dhcp address. I blacklisted the mlx5_core driver and the soft lockups went away. Nate suggested that we might need some additional iommu related patches to address the soft lockup issue. I will build a kernel with those and see if I have any success. So, looks like qcom_emac driver is not at fault here.
