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.

v1:
