The body is missing. The subject states what changed, but not why.
What is the motivation for switching from tst_cmd() to
NETDEV_SET_STATE() here? Patches 3-6 remove the "ip" command
dependency entirely, so presumably this is a step toward that goal,
but this commit stands alone and should explain the reason.

This patch needs revision.

Pre-existing issues noticed in the surrounding code (not introduced
by this patch):

- testcases/network/sockets/xfrm02.c in try_corrupt() -- usleep(30000)
  used to wait for the espintcp strparser to process buffered data.
  Ground Rule 2 prohibits sleep-based synchronization. An
  exponential-backoff polling loop on the processed data would be
  more robust under load.

- testcases/network/sockets/xfrm03.c in try_corrupt() -- same
  usleep(30000) for the same reason.
