Subject: [PATCH net-next] mlxsw: spectrum: Change IP2ME CPU policer rate and burst size values
Date: Mon, 18 Feb 2019 07:19:44 +0000 [thread overview]
Message-ID: <20190218071925.14727-1-idosch@mellanox.com> (raw)
From: Shalom Toledo <shalomt@mellanox.com>
The IP2ME packet trap is triggered by packets hitting local routes.
After evaluating current defaults used by the driver it was decided to
reduce the amount of traffic generated by this trap to 1Kpps and
increase the burst size. This is inline with similarly deployed systems.
