Are you sure, that you are using THE HARP driverS? The PCA200E board
supports only UBR (well it kinda supports CBR on one channel, but this
channel will stall all other channels). The ENI boards could support CBR,
but the driver actually doesn't - it just uses the 0th transmit channel
and does UBR for all traffic. As far as I have seen, of the drivers
that are in the tree only idt seems to support CBR.

Of all the HARP drivers only the Prosum actually does something other than
UBR.
