From 288827d53e8edcca94caf6a507105fcbd20f419d Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 3 Jul 2020 00:39:47 +0100 Subject: [PATCH] rxrpc: Allow multiple client connections to the same peer Allow the number of parallel connections to a machine to be expanded from a single connection to a maximum of four. This allows up to 16 calls to be in progress at the same time to any particular peer instead of 4.
