Control packet length check for PCIe_VDM

[gilbert0225]

Via 'Management Component Transport Protocol (MCTP) PCIe VDM Transport Binding Specification', PCIe VDM Header only manger the Length with WORD aligned size.

So, following len check will be failed always, for the MCTP control packets which are delivered thru PCIe VDM

• if (len != sizeof(struct mctp_ctrl_cmd_set_endpoint_id_req)) {
• if (len != sizeof(struct mctp_ctrl_msg_hdr)) {
• if (len != sizeof(struct mctp_ctrl_cmd_get_version_req)) {
• if (len != sizeof(struct mctp_ctrl_msg_hdr)) {

How about to change the len check as below ?

• if (len < sizeof(struct mctp_ctrl_cmd_set_endpoint_id_req)) {
• if (len < sizeof(struct mctp_ctrl_msg_hdr)) {
• if (len < sizeof(struct mctp_ctrl_cmd_get_version_req)) {
• if (len < sizeof(struct mctp_ctrl_msg_hdr)) {
