From 84e009042d0f3dfe91bec60bcd208ee3f866cbcd Mon Sep 17 00:00:00 2001 From: Maurizio Lombardi Date: Mon, 17 Feb 2025 17:08:27 +0100 Subject: nvme-tcp: add basic support for the C2HTermReq PDU Previously, the NVMe/TCP host driver did not handle the C2HTermReq PDU, instead printing "unsupported pdu type (3)" when received. This patch adds support for processing the C2HTermReq PDU, allowing the driver to print the Fatal Error Status field. Example of output: nvme nvme4: Received C2HTermReq (FES = Invalid PDU Header Field) Signed-off-by: Maurizio Lombardi Reviewed-by: Sagi Grimberg Signed-off-by: Keith Busch --- include/linux/nvme-tcp.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include') diff --git a/include/linux/nvme-tcp.h b/include/linux/nvme-tcp.h index e07e8978d691..e435250fcb4d 100644 --- a/include/linux/nvme-tcp.h +++ b/include/linux/nvme-tcp.h @@ -13,6 +13,8 @@ #define NVME_TCP_ADMIN_CCSZ SZ_8K #define NVME_TCP_DIGEST_LENGTH 4 #define NVME_TCP_MIN_MAXH2CDATA 4096 +#define NVME_TCP_MIN_C2HTERM_PLEN 24 +#define NVME_TCP_MAX_C2HTERM_PLEN 152 enum nvme_tcp_pfv { NVME_TCP_PFV_1_0 = 0x0, -- cgit v1.2.3
