Subject: [PATCH net-next v2 02/16] mlxsw: reg: Add Monitoring Precision Time Protocol Trap Register
Date: Sun, 30 Jun 2019 09:04:46 +0300 [thread overview]
Message-ID: <20190630060500.7882-3-idosch@idosch.org> (raw)
In-Reply-To: <20190630060500.7882-1-idosch@idosch.org>
From: Petr Machata <petrm@mellanox.com>
This register is used for configuring under which trap to deliver PTP
packets depending on type of the packet.
