Hi NVIDIA Support Team, I am working on the Jetson Thor platform and require standard Linux traffic control features for network emulation (specifically Netem for delay/loss and TBF for bandwidth limiting). When attempting to use tc, I encounter errors indicating missing kernel support. I have verified the kernel configuration and found that these schedulers are not set: 复制 $ zcat /proc/config.gz | grep -E "CONFIG_NET_SCH_NETEM|CONFIG_NET_SCH_TBF" # CONFIG_NET_SCH_TBF is not set # CONFIG_NET_SCH_NETEM is not set Since I am on a very recent/development build, I would like to know the recommended way to enable these features. Questions: Is there a way to enable sch_netem and sch_tbf without a full kernel recompilation (e.g., are there loadable modules available)? If recompilation is required for Kernel 6.8.12-tegra, could you provide the specific instructions or source location for this version? Given that this is L4T R38, are there any changes in the kernel build process (compared to R35/R36) that I should be aware of? System Information: Device: Jetson Thor L4T Version: R38 (release), REVISION: 2.0 (GCID: 41844464) Kernel Version: 6.8.12-tegra Date: Fri Aug 22 00:55:42 UTC 2025

[Jetson Thor] Missing CONFIG_NET_SCH_NETEM and CONFIG_NET_SCH_TBF support on L4T R38.2.0 (Kernel 6.8)
