Subject: [PATCH v3 4/5] ntb_perf: increase sleep time from one milli sec to one sec
Date: Tue,  5 May 2020 23:21:51 -0500	[thread overview]
Message-ID: <1588738912-24827-5-git-send-email-sanju.mehta@amd.com> (raw)
In-Reply-To: <1588738912-24827-1-git-send-email-sanju.mehta@amd.com>

After trying to send commands for a maximum of MSG_TRIES
re-tries, link-up fails due to short sleep time(1ms) between
re-tries. Hence increasing the sleep time to one second providing
sufficient time for perf link-up.
