Subject: [PATCH net-next,v2 0/6] Add software backchannel and mlx5e HV VHCA
 stats

This patch set adds paravirtual backchannel in software in pci_hyperv,
which is required by the mlx5e driver HV VHCA stats agent.

The stats agent is responsible on running a periodic rx/tx packets/bytes
stats update.

Dexuan Cui (1):
  PCI: hv: Add a paravirtual backchannel in software

Haiyang Zhang (5):
  PCI: hv: Add a Hyper-V PCI interface driver for software backchannel
    interface
  net/mlx5: Add wrappers for HyperV PCIe operations
  net/mlx5: Add HV VHCA infrastructure
  net/mlx5: Add HV VHCA control agent
  net/mlx5e: Add mlx5e HV VHCA stats agent
