The method to report device information to the log is the same for both
physical and virtual functions. The implementation is however open coded
in each code path, break out the reporting logic to a helper
function to reduce code duplication.

Previously only one metadata type was supported, now we need support many
different types of metadata, in order to achieve portability and
extensibilit, so adding the new struct nfp_meta_parsed to modify the logic
of parse metadata

+The NFP packet metadata format

+The packet metadata starts with a field type header that can contain up-to

The firmware supplies VLAN strip information is stroed in
packet metadata. The field of this VLAN metadata includes
VLAN TPID, VLAN TCI and offload flag.
The new metadata type is NFP_NET_META_VLAN.

From: Peng Zhang <peng.zhang@corigine.com>
The VLAN information can be stored in the descriptor or in the metadata.
Add a new VLAN strip V2 bit to distinguish them. When VLAN strip is set,
the vlan information is stored in the descriptor. When VLAN strip V2 is
set, it is stored in the metadata.

As the firmware with NFD3 change, using the metadata sends
the VLAN info to the nic to achieve the VLAN offload insert.
The VLAN INFO consists of 16bit TPID + 16bit TCI

The firmware support VLAN insert with the descriptor or the metadata.
So adding a NFP_NET_CFG_CTRL_RXVLAN_V2 bit to distinguish them. When
VLAN insert is set, sending the vlan information with the descriptor.
When VLAN insert V2 is set, sending it with the metadata.
Now NFP_NET_CFG_CTRL_L2SWITCH_LOCAL isn't used, so 0x1 << 23 is used
by NFP_NET_CFG_CTRL_RXVLAN_V2.

The firmware supplies VLAN insert information as packet metadata.
The field of this VLAN metadata includes VLAN TPID and VLAN
TCI.
Configuration control bit NFP_NET_CFG_CTRL_TXVLAN_V2 is to
signal availability of VLAN insert features of the firmware.
This feature already was implemented with NFD3, now it can be
supported with NFDk.
