Cong Wang 6c1128b87d pktgen: correctly handle failures when adding a device ... [ Upstream commit 604dfd6efc ] 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) Cc: David S.
