With classification being pushed down into the DLS layer for softrings, we're facing a point where we're doing double the amount of work in sanity checking IP packets.
Whilst the PEF project would solve this for us, PEF has been put in suspended animation for the time being :-( Does anyone have any thoughts on how we might architect DLS/IP to try and eliminate this double-work effort in the mean time? This is similar to another idea that Garrett brought up recently where we make the entry requirements for ip_input() quite different for those of ip_rput() and use mac/dls layer to cover the those bases that ip_rput() would do for legacy device drivers. Thoughts? (This was motivated by the extract of DLS from Brendan's email showing the OK_PTR and msgpullup.)
