NVM Express is high speed interface for accessing solid state drives.
|
|
NVM Express specifications are maintained by NVM Express industry
|
|
association at http://www.nvmexpress.org.
|
|
|
|
This file adds support to dissect NVM Express over fabrics packets
|
|
for RDMA. This adds very basic support for dissecting commands
|
|
completions.
|
|
|
|
Current dissection supports dissection of
|
|
(a) NVMe cmd and cqe
|
|
(b) NVMe Fabric command and cqe
|
|
As part of it, it also calculates cmd completion latencies.
|
|
|
|
This protocol is similar to iSCSI and SCSI dissection where iSCSI is
|
|
transport protocol for carying SCSI commands and responses. Similarly
|
|
NVMe Fabrics - RDMA transport protocol carries NVMe commands.
