Re: CVS commit: src/sys/net
I predict that in the near future the network stack will act like a "batch" manner; instead of moving layers for a single packet, pass a batch of packets to the next layer; each layer processes a batch of packets in a loop and stay longer (than now) holding a relevant context object cached. In such a model the relative cost of indirection will become nothing.
