Subject: mlxsw: pci: Add mirror reason field to CQEv2
Patch-mainline: v5.9-rc1
Git-commit: a76423a144a8a109cffbd7311c3278f8a856b25f
References: bsc#1176774
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.
