Subject: [PATCH iproute2 net-next v1 3/6] taprio: Add support for enabling offload mode
Date: Tue, 28 May 2019 10:52:51 -0700 [thread overview]
Message-ID: <1559065974-28521-3-git-send-email-vedang.patel@intel.com> (raw)
In-Reply-To: <1559065974-28521-1-git-send-email-vedang.patel@intel.com>
From: Vinicius Costa Gomes <vinicius.gomes@intel.com>
This allows a new parameter to be passed to taprio, "offload",
accepting a hexadecimal number which selects the offloading flags
thats should be enabled.
