Balandin (3):
nvme-tcp-offload: Add device scan implementation
nvme-tcp-offload: Add queue level implementation
nvme-tcp-offload: Add IO level implementation
Shai Malin (5):
nvme-tcp-offload: Add nvme-tcp-offload - NVMeTCP HW offload ULP
nvme-qedn: Add qedn - Marvell's NVMeTCP HW offload
block - which is used for the FW to notify the driver with
the producer update of the FW CQE chain.
The FW fast-path queues are based on qed_chain.h

This patch introduces the NVMeTCP device and PF level HSI and HSI
functionality in order to initialize and interact with the HW device.
This patch is based on the qede, qedr, qedi, qedf drivers HSI.
