The return value of pktgen_add_device() is not checked, so
even if we fail to add some device, for example, non-exist one,
we still see "OK:...". This patch fixes it.
After this patch, I got:
# echo "add_device non-exist" > /proc/net/pktgen/kpktgend_0
-bash: echo: write error: No such device
# cat /proc/net/pktgen/kpktgend_0
Running:
Stopped:
Result: ERROR: can not add device non-exist
# echo "add_device eth0" > /proc/net/pktgen/kpktgend_0
# cat /proc/net/pktgen/kpktgend_0
Running:
Stopped: eth0
Result: OK: add_device=eth0
(Candidate for -stable)
