[PATCH 0/7] Small improvements to IOV handling

[David Gibson <david@gibson.dropbear.id.au>]

Laurent's changes to split TCP buffers into various components with
IOVs is now merged.  This series has a batch of small cleanups to make
the handling of this slightly nicer.  These are preliminaries to doing
something similar with the UDP buffers.

Note that patch 7/7 might interfere with the experiments to work out
what is going wrong with the odd batching / performance issues we've
seen.  We can leave it off for the time being if that's a problem.

David Gibson (7):
  checksum: Use proto_ipv6_header_psum() for ICMPv6 as well
  tap: Split tap specific and L2 (ethernet) headers
  treewide: Standardise variable names for various packet lengths
  tcp: Simplify packet length calculation when preparing headers
  tap, tcp: (Re-)abstract TAP specific header handling
  iov: Helper macro to construct iovs covering existing variables or
    fields
  tcp: Update tap specific header too in tcp_fill_headers[46]()
