Subject: [PATCH v2 resend 0/4] vdpa:/mlx5: Add debugfs subtree 

First patch fixes a copy paste error causing VLAN tagged packets to no
be filtered.In addition it modifies the logic so VLAN filtering is
enforced only if VIRTIO_NET_F_CTRL_VLAN is negotiated.

Following three patches add debugfs subtree.
First one just moves definitions to a new header file. These definitions
are needed for following patches.
Second patch adds entries to read flow table number and TIR number.
Third patch adds multicast and unicast packets and bytes counters for
for each untagged or VLAN tagged incoming traffic. This is depends on
MLX5_VDPA_STEERING_DEBUG config option and is off by default.

v1->v2:
1. Enforce VLAN filtering onl if VIRTIO_NET_F_CTRL_VLAN is negotiated.
2. Error flow cleanups.

Eli Cohen (4):
  vdpa/mlx5: Fix rule forwarding VLAN to TIR
  vdpa/mlx5: Move some definitions to a new header file
  vdpa/mlx5: Add debugfs subtree
  vdpa/mlx5: Add RX counters to debugfs
