From 19ffa01c9c45861ad6b181323e0d36904298e326 Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 4 Apr 2016 14:00:36 +0100 Subject: rxrpc: Use structs to hold connection params and protocol info Define and use a structure to hold connection parameters. This makes it easier to pass multiple connection parameters around. Define and use a structure to hold protocol information used to hash a connection for lookup on incoming packet. Most of these fields will be disposed of eventually, including the duplicate local pointer. Whilst we're at it rename "proto" to "family" when referring to a protocol family.
