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
