your patch will not prevent the first ping to empty the token bucket,
because burst is still 0, which is larger than dst->rate_token, and since
XRLIM_BURST_FACTOR times the timeout (which is 6*0=0 in that case) is the
token maximum, it will be truncated to 0, causing the following packets (if
in time) to be dropped.
