Subject: [PATCH v2 net-next] net/ncsi: add response handlers for PLDM over NC-SI
Date: Fri, 30 Aug 2019 20:50:51 +0000 [thread overview]
Message-ID: <CH2PR15MB3686A26D4BB64D8959B519B6A3BD0@CH2PR15MB3686.namprd15.prod.outlook.com> (raw)
This patch adds handlers for PLDM over NC-SI command response.
This enables NC-SI driver recognizes the packet type so the responses
don't get dropped as unknown packet type.
PLDM over NC-SI are not handled in kernel driver for now, but can be
passed back to user space via Netlink for further handling.
