Subject: [PATCH net-next 08/11] mlxsw: reg: Add new trap action
Date: Sun,  7 Jul 2019 10:58:25 +0300	[thread overview]
Message-ID: <20190707075828.3315-9-idosch@idosch.org> (raw)
In-Reply-To: <20190707075828.3315-1-idosch@idosch.org>

From: Ido Schimmel <idosch@mellanox.com>

Subsequent patches will add discard traps support in mlxsw. The driver
cannot configure such traps with a normal trap action, but need to use
exception trap action, which also increments an error counter.
