Subject: [PATCH iproute2 net-next v5 3/5] taprio: add support for setting txtime_delay.
Date: Thu, 18 Jul 2019 12:55:41 -0700 [thread overview]
Message-ID: <1563479743-8371-3-git-send-email-vedang.patel@intel.com> (raw)
In-Reply-To: <1563479743-8371-1-git-send-email-vedang.patel@intel.com>
This adds support for setting the txtime_delay parameter which is useful
for the txtime offload mode of taprio.
