Misc updates for mlx5 driver
1) Add TX max rate support for MQPRIO channel mode
2) Trivial TC action and modify header refactoring
3) TC support for accept action in fdb offloads
4) Allow single IRQ for PCI functions
5) Bridge offload: Pop PVID VLAN header on egress miss
Vlad Buslov says:
=================
With current architecture of mlx5 bridge offload it is possible for a
packet to match in ingress table by source MAC (resulting VLAN header push
in case of port with configured PVID) and then miss in egress table when
destination MAC is not in FDB. Due to the lack of hardware learning in
NICs, this, in turn, results packet going to software data path with PVID
VLAN already added by hardware. This doesn't break software bridge since it
accepts either untagged packets or packets with any provisioned VLAN on
ports with PVID, but can break ingress TC, if affected part of Ethernet
header is matched by classifier.
Improve compatibility with software TC by restoring the packet header on
egress miss. Effectively, this change implements atomicity of mlx5 bridge
offload implementation - packet is either modified and redirected to
destination port or appears unmodified in software.

qed: Add '_GTT' suffix to the IRO RAM macros
GTT (Global translation table) is a fast-access window in the BAR into
the register space, which only maps certain register addresses.
This change helps enforce that only those addresses which are indeed
mapped by the GTT are being accessed through it.
Adding the '_GTT' suffix to the IRO FW memory (“RAM”) macros that
access GTT-able region in FW memories (“RAM”) and use GTT macros

Justin Iurman says:
====================
Support for the ip6ip6 encapsulation of IOAM
v2:
- add prerequisite patches
- keep uapi backwards compatible by adding two new attributes
- add more comments to document the ioam6_iptunnel uapi
In the current implementation, IOAM can only be inserted directly (i.e., only
inside packets generated locally) by default, to be compliant with RFC8200.
This patch adds support for in-transit packets and provides the ip6ip6
encapsulation of IOAM (RFC8200 compliant). Therefore, three ioam6 encap modes
are defined:
- inline: directly inserts IOAM inside packets (by default).
- encap: ip6ip6 encapsulation of IOAM inside packets.
- auto: either inline mode for packets generated locally or encap mode for
in-transit packets.
With current iproute2 implementation, it is configured this way:
$ ip -6 r [...] encap ioam6 trace prealloc [...]
The old syntax does not change (for backwards compatibility) and implicitly uses
the inline mode. With the new syntax, an encap mode can be specified:
(inline mode)
$ ip -6 r [...] encap ioam6 mode inline trace prealloc [...]
(encap mode)
$ ip -6 r [...] encap ioam6 mode encap tundst fc00::2 trace prealloc [...]
(auto mode)
$ ip -6 r [...] encap ioam6 mode auto tundst fc00::2 trace prealloc [...]
A tunnel destination address must be configured when using the encap mode or the
auto mode.

This patch set adds support for modifying a VLAN ID at the egress stage
of Ocelot/Felix switch ports. It is useful for replicating a packet on
multiple ports, and each egress port sends it using a different VLAN ID.
Tested by rewriting the VLAN ID of both
(a) packets injected from the CPU port
(b) packets received from an external station on a front-facing port
Adding a selftest to make sure it doesn't bit-rot, and if it does, that
it can be traced back easily.

net: dsa: tag_ocelot: set the classified VLAN during xmit
Currently, all packets injected into Ocelot switches are classified to
VLAN 0, regardless of whether they are VLAN-tagged or not. This is
because the switch only looks at the VLAN TCI from the DSA tag.
VLAN 0 is then stripped on egress due to REW_TAG_CFG_TAG_CFG. There are
2 cases really, below is the explanation for ocelot_port_set_native_vlan:
- Port is VLAN-aware, we set REW_TAG_CFG_TAG_CFG to 1 (egress-tag all
frames except VID 0 and the native VLAN) if a native VLAN exists, or
to 3 otherwise (tag all frames, including VID 0).
- Port is VLAN-unaware, we set REW_TAG_CFG_TAG_CFG to 0 (port tagging
disabled, classified VLAN never appears in the packet).
One can already see an inconsistency: when a native VLAN exists, VID 0
is egress-untagged, but when it doesn't, VID 0 is egress-tagged.
So when we do this:
ip link add br0 type bridge vlan_filtering 1
ip link set swp0 master br0
bridge vlan del dev swp0 vid 1
bridge vlan add dev swp0 vid 1 pvid # but not untagged
and we ping through swp0, packets will look like this:
MAC > 33:33:00:00:00:02, ethertype 802.1Q (0x8100): vlan 0, p 0,
ethertype 802.1Q (0x8100), vlan 1, p 0, ethertype IPv6 (0x86dd),
ICMP6, router solicitation, length 16
So VID 1 frames (sent that way by the Linux bridge) are encapsulated in
a VID 0 header - the classified VLAN of the packets as far as the hw is
concerned. To avoid that, what we really need to do is stop injecting
packets using the classified VLAN of 0.
This patch strips the VLAN header from the skb payload, if that VLAN
exists and if the port is under a VLAN-aware bridge. Then it copies that
VLAN header into the DSA injection frame header.
A positive side effect is that VCAP ES0 VLAN rewriting rules now work
for packets injected from the CPU into a port that's under a VLAN-aware
bridge, and we are able to match those packets by the VLAN ID that was
sent by the network stack, and not by VLAN ID 0.

net: mscc: ocelot: write full VLAN TCI in the injection header
The VLAN TCI contains more than the VLAN ID, it also has the VLAN PCP

net: mscc: ocelot: support egress VLAN rewriting via VCAP ES0
Currently the ocelot driver does support the 'vlan modify' action, but
in the ingress chain, and it is offloaded to VCAP IS1. This action
changes the classified VLAN before the packet enters the bridging
service, and the bridging works with the classified VLAN modified by
VCAP IS1.
That is good for some use cases, but there are others where the VLAN
must be modified at the stage of the egress port, after the packet has
exited the bridging service. One example is simulating IEEE 802.1CB
active stream identification filters ("active" means that not only the
rule matches on a packet flow, but it is also able to change some
headers). For example, a stream is replicated on two egress ports, but
they must have different VLAN IDs on egress ports A and B.
This seems like a task for the VCAP ES0, but that currently only
supports pushing the ES0 tag A, which is specified in the rule. Pushing
another VLAN header is not what we want, but rather overwriting the
existing one.
It looks like when we push the ES0 tag A, it is actually possible to not
only take the ES0 tag A's value from the rule itself (VID_A_VAL), but
derive it from the following formula:
ES0_TAG_A = Classified VID + VID_A_VAL
Otherwise said, ES0_TAG_A can be used to increment with a given value
the VLAN ID that the packet was already classified to, and the packet
will have this value as an outer VLAN tag. This new VLAN ID value then
gets stripped on egress (or not) according to the value of the native
VLAN from the bridging service.
While the hardware will happily increment the classified VLAN ID for all
packets that match the ES0 rule, in practice this would be rather
insane, so we only allow this kind of ES0 action if the ES0 filter
contains a VLAN ID too, so as to restrict the matching on a known
classified VLAN. If we program VID_A_VAL with the delta between the
desired final VLAN (ES0_TAG_A) and the classified VLAN, we obtain the
desired behavior.
It doesn't look like it is possible with the tc-vlan action to modify
the VLAN ID but not the PCP. In hardware it is possible to leave the PCP
to the classified value, but we unconditionally program it to overwrite
it with the PCP value from the rule.
