Subject: [PATCH net-next 11/13] mlxsw: pci: Add mirror reason field to CQEv2

From: Ido Schimmel <idosch@...lanox.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.
