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 10/10 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.
Changes since v1:
* Added new patch removing some unused structures
* Added two new patches cleaning up some endianness confusion
* Added a bunch of missing cases to standardisation of length
variable names
* Assorted minor revisions based on Stefano's review
David Gibson (10):
checksum: Use proto_ipv6_header_psum() for ICMPv6 as well
tap: Split tap specific and L2 (ethernet) headers
tap: Remove unused structs tap_msg, tap_l4_msg
treewide: Remove misleading and redundant endianness notes
checksum: Make csum_ip4_header() take a host endian length
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]()
