This is a first draft of the first part of implementing a more general
flow table (connection tracking) as described at:
https://pad.passt.top/p/NewForwardingModel
This is by no means complete. So far it doesn't really do anything
new, it just reorganizes the TCP connection table to be closer to the
more general flow table.
Still it's ready for preliminary review.
David Gibson (8):
tap: Don't clobber source address in tap6_handler()
tap: Pass source address to protocol handler functions
tcp: More precise terms for addresses and ports
tcp, udp: Don't include destination address in partially precomputed
csums
tcp, udp: Don't pre-fill IPv4 destination address in headers
tcp: Track guest-side correspondent address
tcp, flow: Introduce struct demiflow
tcp, flow: Perform TCP hash calculations based on demiflow structure
