pktgen: make /proc/net/pktgen/pgctrl report fail on invalid input
Giving /proc/net/pktgen/pgctrl an invalid command just returns shell success and prints a warning in dmesg. This is not very useful for shell scripting, as it can only detect the error by parsing dmesg. Instead return -EINVAL when the command is unknown, as this provides userspace shell scripting a way of detecting this. Also bump version tag to 2.75, because (1) reading /proc/net/pktgen/pgctrl output this version number which would allow to detect this small semantic change, and (2) because the pktgen version tag have not been updated since 2010.
