I know it affected the TX2, with the exact same symptoms It could affect Xavier modules as well. The workaround is to disable LLDP on by adding LLDP=no to the [Network] section for the interface. See https://github.com/OE4T/meta-tegra/issues/146 The workaround didn't get back-ported to the thud-l4t-r32.3.1 branch.

Since this is BSP-related, opening an issue at https://github.com/OE4T/meta-tegra/issues might work better. Regards -Matt
