From 2b59f58e34e78abec2bccd2413ae9e7ea509a855 Mon Sep 17 00:00:00 2001 From: Ursula Braun Date: Thu, 22 Nov 2018 10:26:39 +0100 Subject: net/smc: short wait for late smc_clc_wait_msg After sending one of the initial LLC messages CONFIRM LINK or ADD LINK, there is already a wait for the LLC response. It does not make sense to wait another long time for a CLC DECLINE. Thus this patch introduces a shorter wait time for these cases. Signed-off-by: Ursula Braun Signed-off-by: David S.
