[PATCH 00/16] More flow table preliminaries: address handling improvements

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

Here's another batch of cleanups and tweaks in preparation for the
flow table.  This set focuses on improved helpers for handling
addresses, particularly in the TCP splice path.

David Gibson (16):
  treewide: Use sa_family_t for address family variables
  tcp, udp: Don't precompute port remappings in epoll references
  flow: Add helper to determine a flow's protocol
  tcp_splice: Simplify clean up logic
  inany: Helper to test for IPv4 or IPv6 loopback address
  tcp, tcp_splice: Helpers for getting sockets from the pools
  tcp_splice: More specific variable names in new splice path
  tcp_splice: Fix incorrect parameter comment for tcp_splice_connect()
  tcp_splice: Merge tcp_splice_new() into its caller
  tcp_splice: Improve error reporting on connect path
  inany: Add inany_ntop() helper
  tcp_splice: Improve logic deciding when to splice
  util: Provide global constants for IPv4 loopback and unspecified
    address
  inany: Introduce union sockaddr_inany
  tcp, tcp_splice: Better construction of IPv4 or IPv6 sockaddrs
  inany: Extend inany_from_af to easily set unspecified addresses
