Subject: [PATCH net-next 07/14] devlink: Add layer 3 control packet traps
Date: Fri, 29 May 2020 21:36:42 +0300 [thread overview]
Message-ID: <20200529183649.1602091-8-idosch@idosch.org> (raw)
In-Reply-To: <20200529183649.1602091-1-idosch@idosch.org>
From: Ido Schimmel <idosch@mellanox.com>
Add layer 3 control packet traps such as ARP and DHCP, so that capable
device drivers could register them with devlink. Add documentation for
every added packet trap and packet trap group.
Signed-off-by: Ido Schimmel <idosch@mellanox.com>
