This small series includes fixes for creation of veth pairs for networkless kernels & adds tests for turning the different network interface features on and off in selftests/net/netdevice.sh script.
Changes in v5: Rectify the syntax for ip add link. Fix the veth_created condition check.
Changes in v4: https://lore.kernel.org/all/20240807175717.7775-1-jain.abhinav177@gmail.com/
Move veth creation/removal to the main shell script. Tested using vng on a networkless kernel and the script works, sample output below the changes.
Changes in v3: https://lore.kernel.org/all/20240614113240.41550-1-jain.abhinav177@gmail.com...
Add a check for netdev, create veth pair for testing. Restore feature to its initial state.
Changes in v2: https://lore.kernel.org/all/20240609132124.51683-1-jain.abhinav177@gmail.com...
Remove tail usage; use read to parse the features from temp file.
