You're using a broken version of iproute (well, actually the kernel is
broken, but a new iproute fixes it).
The statistics mean:
period: number of times the class went to active state (no packets
queued -> packets queued)
work: number of bytes handled by real-time and link-sharing criteria
rtwork: number of bytes handled by real-time criterion
level: level in the class hierarchy
When using only linear service curves "m2" is the equivalent to rate.
