I=92ve just pushed support for an overhead parameter; both cake itself = and the iproute2 module. I took the opportunity to put in a minor = optimisation for the cell-framing compensation as well. The iproute2 support isn=92t as complete as I=92d eventually like. = However, you can specify a numerical overhead (positive or negative, = within sane limits) independently of whether ATM framing compensation is = turned on or off. There are also two =93easy mode=94 keywords: =93raw=94 is equivalent to = =93noatm overhead 0=94, and =93conservative=94 means =93atm overhead = 48=94. The latter will almost certainly overestimate the actual = overhead. The help text for cake also now indicates the default options more = clearly. Also pushed is a one-line build fix for iproute2. - Jonathan Morton
