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.

We get the full line rate with the HARP VJ>stack without any patches. Moreover it has been tested up to 4K PVC. Of all the HARP drivers only the Prosum actually does something other than UBR. harti -- harti brandt, http://www.fokus.gmd.de/research/cc/cats/employees/hartmut.brandt/private brandt@fokus.fraunhofer.de, harti@freebsd.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-atm" in the body of the message
