tc transparently maps the software priority number to hardware. Update
it to pass the major priority which is what most drivers expect. Update
drivers too so they do not need to lshift the priority field of the
flow_cls_common_offload object. The stmmac driver is an exception, since
this code assumes the tc software priority is fine, therefore, lshift it
just to be conservative.

Flower rules on the NFP firmware are able to match on an IP protocol
field. When parsing rules in the driver, unknown IP protocols are only
rejected when further matches are to be carried out on layer 4 fields, as
the firmware will not be able to extract such fields from packets.
L4 protocol dissectors such as FLOW_DISSECTOR_KEY_PORTS are only parsed if
an IP protocol is specified. This leaves a loophole whereby a rule that
attempts to match on transport layer information such as port numbers but
does not explicitly give an IP protocol type can be incorrectly offloaded
(in this case with wildcard port numbers matches).
Fix this by rejecting the offload of flows that attempt to match on L4
information, not only when matching on an unknown IP protocol type, but
also when the protocol is wildcarded.

NFP firmware does not explicitly match on an ethernet type field. Rather,
each rule has a bitmask of match fields that can be used to infer the
ethernet type.
Currently, if a flower rule contains an unknown ethernet type, a check is
carried out for matches on other fields of the packet. If matches on
layer 3 or 4 are found, then the offload is rejected as firmware will not
be able to extract these fields from a packet with an ethernet type it
does not currently understand.
However, if a rule contains an unknown ethernet type without any L3 (or
above) matches then this will effectively be offloaded as a rule with a
wildcarded ethertype. This can lead to misclassifications on the firmware.
Fix this issue by rejecting all flower rules that specify a match on an
unknown ethernet type.
Further ensure correct offloads by moving the 'L3 and above' check to any
rule that does not specify an ethernet type and rejecting rules with
further matches. This means that we can still offload rules with a
wildcarded ethertype if they only match on L2 fields but will prevent
rules which match on further fields that we cannot be sure if the firmware
will be able to extract.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct nfp_tun_active_tuns {
...
struct route_ip_info {
__be32 ipv4;
__be32 egress_port;
__be32 extra[2];
} tun_info[];
};
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
So, replace the following form:
sizeof(struct nfp_tun_active_tuns) + sizeof(struct route_ip_info) * count
with:
struct_size(payload, tun_info, count)
This code was detected with the help of Coccinelle.

A merge flow is formed from 2 sub flows. The match fields of the merge are
the same as the first sub flow that has formed it, with the actions being
a combination of the first and second sub flow. Therefore, a merge flow
should replace sub flow 1 when offloaded.
Offload valid merge flows by using a new 'flow mod' message type to
replace an existing offloaded rule. Track the deletion of sub flows that
are linked to a merge flow and revert offloaded merge rules if required.

With the merging of 2 sub flows, a new 'merge' flow will be created and
written to FW. The TC layer is unaware that the merge flow exists and will
request stats from the sub flows. Conversely, the FW treats a merge rule
the same as any other rule and sends stats updates to the NFP driver.
Add links between merge flows and their sub flows. Use these links to pass
merge flow stats updates from FW to the underlying sub flows, ensuring TC
stats requests are handled correctly. The updating of sub flow stats is
done on (the less time critcal) TC stats requests rather than on FW stats
update.

When combining 2 sub_flows to a single 'merge flow' (assuming the merge is
valid), the merge flow should contain the same match fields as sub_flow 1
with actions derived from a combination of sub_flows 1 and 2. This action
list should have all actions from sub_flow 1 with the exception of the
output action that triggered the 'implicit recirculation' by sending to
an internal port, followed by all actions of sub_flow 2. Any pre-actions
in either sub_flow should feature at the start of the action list.
Add code to generate a new merge flow and populate the match and actions
fields based on the sub_flows. The offloading of the flow is left to
future patches.

Each flow is given a context ID that the fw uses (along with its cookie)
to identity the flow. The flows stats are updated by the fw via this ID
which is a reference to a pre-allocated array entry.
In preparation for flow merge code, enable the nfp_fl_payload structure to
be accessed via this stats context ID. Rather than increasing the memory
requirements of the pre-allocated array, add a new rhashtable to associate
each active stats context ID with its rule payload.
While adding new code to the compile metadata functions, slightly

FW may receive a packet with its ingress port marked as an internal port.
If a rule does not exist to match on this port, the packet will be sent to
the NFP driver. Modify the flower app to detect packets from such internal
ports and convert the ingress port to the correct kernel space netdev.
At this point, it is assumed that fallback packets from internal ports are
to be sent out said port. Therefore, set the redir_egress bool to true on
detection of these ports.

Currently, it is assumed that fallback packets will be from reprs. Modify
this to allow an app to receive non-repr ports from the fallback channel -
e.g. from an internal port. If such a packet is received, do not update
repr stats.
Change the naming function calls so as not to imply it will always be a
repr netdev returned. Add the option to set a bool value to redirect a
fallback packet out the returned port rather than RXing it. Setting of
this bool in subsequent patches allows the handling of packets falling
back when they are due to egress an internal port.

Recent FW modifications allow the offloading of non repr ports. These
ports exist internally on the NFP. So if a rule outputs to an 'internal'
port, then the packet will recirculate back into the system but will now
have this internal port as it's incoming port. These ports are indicated
by a specific type field combined with an 8 bit port id.
Add private app data to assign additional port ids for use in offloads.
Provide functions to lookup or create new ids when a rule attempts to
match on an internal netdev - the only internal netdevs currently
supported are of type openvswitch. Have a netdev notifier to release
port ids on netdev unregister.
OvS offloads rules that match on internal ports as TC egress filters.
Ensure that such rules are accepted by the driver.

With the introduction of flow_action_for_each pedit actions are no
longer grouped together, instead pedit actions are broken out per
32 byte word. This results in an inefficient use of the action list
that is pushed to hardware where each 32 byte word becomes its own
action. Therefore we combine groups of 32 byte word before sending
the action list to hardware.

Added IANA_VXLAN_UDP_PORT (4789) definition to vxlan header file so it
can be used by drivers instead of local definition.
Updated drivers which locally defined it as 4789 to use it.

Move the definition of the default Geneve udp port from the geneve
source to the header file, so we can re-use it from drivers.
Modify existing drivers to use it.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
size = sizeof(struct foo) + count * sizeof(void *);
instance = alloc(size, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = alloc(struct_size(instance, entry, count), GFP_KERNEL);
Notice that, in this case, variable size is not necessary, hence
it is removed.
This code was detected with the help of Coccinelle.

NFP only supports SWITCHDEV_ATTR_ID_PORT_PARENT_ID, which makes it a
great candidate to be converted to use the ndo_get_port_parent_id() NDO
instead of implementing switchdev_port_attr_get().
Since NFP uses switchdev_port_same_parent_id() convert it to use
netdev_port_same_parent_id().
