[ Upstream commit f7ee799a51ddbcc205ef615fe424fb5084e9e0aa ]
Replace vlan CFI bit with a vlan present bit that indicates the
presence of a vlan tag. Previously the driver incorrectly assumed
that an vlan id of 0 is not matchable, therefore we indicate vlan
presence with a vlan present bit.

Previously we only checked if the vlan id field is present when trying
to match a vlan tag. The vlan id and vlan pcp field should be treated
independently.

The addition of FLOW_DISSECTOR_KEY_ENC_IP to TC flower means that the ToS
and TTL of the tunnel header can now be matched on.
Extend the NFP tunnel match function to include these new fields.

Previously it was not possible to distinguish between mpls ether types and
other ether types. This leads to incorrect classification of offloaded
filters that match on mpls ether type. For example the following two
filters overlap:
# tc filter add dev eth0 parent ffff: \
protocol 0x8847 flower \
action mirred egress redirect dev eth1
# tc filter add dev eth0 parent ffff: \
protocol 0x0800 flower \
action mirred egress redirect dev eth2
The driver now correctly includes the mac_mpls layer where HW stores mpls
fields, when it detects an mpls ether type. It also sets the MPLS_Q bit to
indicate that the filter should match mpls packets.

Compile Geneve match fields for offloading to the NFP. The addition of
Geneve overflows the 8 bit key_layer field, so apply extended metadata to
the match cmsg allowing up to 32 more key_layer fields.
Rather than adding new Geneve blocks, move the vxlan code to generic ipv4
udp tunnel structs and use these for both vxlan and Geneve.
Matches are only supported when specifically mentioning well known port
6081. Geneve tunnel options are not yet included in the match.
Only offload Geneve if the fw supports it - include check for this.

The tunnel dest IP is required for separate offload to the NFP. It is
already verified that a dest IP must be present and must be an exact
match in the flower rule. Therefore, we can just extract the IP from the
generated offload rule and remove the unused mask variable. The function
is then no longer required to return the IP separately.
Because tun_dst is localised to tunnel matches, move the declaration to
the tunnel if branch.

Port matching is selected by default on every rule so remove check for it
and delete 'else' side of the statement. Remove nfp_flower_meta_one as now
it will not feature in the code. Rename nfp_flower_meta_two given that one
has been removed.
'Additional metadata' if statement can never be true so remove it as well.

Generate a list of MAC addresses of netdevs that could be used as VXLAN
tunnel end points. Give offloaded MACs an index for storage on the NFP in
the ranges:
0x100-0x1ff physical port representors
0x200-0x2ff VF port representors
0x300-0x3ff other offloads (e.g. vxlan netdevs, ovs bridges)
Assign phys and vf indexes based on unique 8 bit values in the port num.
Maintain list of other netdevs to ensure same netdev is not offloaded
twice and each gets a unique ID without exhausting the entries. Because
the IDs are unique but constant for a netdev, any changes are implemented
by overwriting the index on NFP.
