Subject: [PATCH] Drivers: hv: utils: reduce HV_UTIL_NEGO_TIMEOUT timeout
Date: Mon, 10 Oct 2016 18:20:36 +0200 [thread overview]
Message-ID: <1476116436-31770-1-git-send-email-vkuznets@redhat.com> (raw)
I discovered that at least WS2016TP5 host has 60 seconds timeout for the
ICMSGTYPE_NEGOTIATE message so we need to lower guest's timeout a little
bit to make sure we always respond in time. Let's make it 55 seconds.
