We'll want that for various future changes. This series makes a similar split for UDP buffers, which we'll want in order to allow dual-stack UDP sockets, amongst other things. This is based on my earlier series of cleanups for the TCP buffer handling. Changes since v1: * Rebase on v2 of the TCP iov and buffer handling cleanups * Rename udp_payload and udp_meta structures to _t for more consistency with tcp.c * Other minor changes based on Stefano's review David Gibson (7): test: Allow sftp via vsock-ssh in tests udp: Split tap-bound UDP packets into multiple buffers using io vector udp: Combine initialisation of IPv4 and IPv6 iovs udp: Explicitly set checksum in guest-bound UDP headers udp: Share payload buffers between IPv4 and IPv6 udp: Use the same buffer for the L2 header for all frames udp: Single buffer for IPv4, IPv6 headers and metadataApplied. -- Stefano
