	Do you have a DDTS I can reference?

	I agree that Cisco should actually take more serious ownership
of these issues within a customers network.  They're selling us
these software/hw and claiming that we can obtain a particular SLA
level.  Yet they can't seem to add in some code that says

	if  (ifc->in_bps > ifc->phy_speed || ifc->out_bps > ifc->phy_speed)

	If they added this code, they'd find these bugs in their
labs instead of in our networks.
