Subject: [PATCH net-next 11/13] mlxsw: pci: Add mirror reason field to CQEv2
Date: Tue, 14 Jul 2020 17:21:04 +0300 [thread overview]
Message-ID: <20200714142106.386354-12-idosch@idosch.org> (raw)
In-Reply-To: <20200714142106.386354-1-idosch@idosch.org>
From: Ido Schimmel <idosch@mellanox.com>
The Completion Queue Element version 2 (CQEv2) includes a field called
'mirror_reason' which indicates why the packet was mirrored to the CPU.
Add the field so that it can be used by a later patch.
