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.
