Subject: pktgen and tos

Here's a half-arsed bug report, in case someone is bored.

At least in my hacked up pktgen, you cannot set a one-digit tos,
because the parser fails if length is not 2 digits.

echo tos 4 > /proc/net/pktgen/rddVR2 && cat /proc/net/pktgen/rddVR2

Result: ERROR: tos must be 00-ff

If you use '04' instead, it works.  In my case, it will be easier to hack user-space
to deal with this than fix pktgen, but I thought someone might want to fix it proper.

Also, could be that upstream code doesn't have this limitation...
