[ Upstream commit f26f719a36e56381a1f4230e5364e7ad4d485888 ]
When calling qede_parse_actions() then the
return code was only used for a non-zero check,
and then -EINVAL was returned.
qede_parse_actions() can currently fail with:
* -EINVAL
* -EOPNOTSUPP
This patch changes the code to use the actual
return code, not just return -EINVAL.
The blaimed commit broke the implicit assumption
that only -EINVAL would ever be returned.
Only compile tested.

This big patch sprinkles const on local variables and
function arguments which may refer to netdev->dev_addr.
Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.
Some of the changes here are not strictly required - const
is sometimes cast off but pointer is not used for writing.
It seems like it's still better to add the const in case
the code changes later or relevant -W flags get enabled
for the build.
No functional changes.

Now that BPF program/link management is centralized in generic net_device
code, kernel code never queries program id from drivers, so
XDP_QUERY_PROG/XDP_QUERY_PROG_HW commands are unnecessary.

the xdp_attachment_query().

The qede driver supports for ethtool_rx_flow_spec and flower, both
codebases look very similar.
This patch uses the ethtool_rx_flow_rule() infrastructure to remove the
duplicated ethtool_rx_flow_spec parser and consolidate ACL offload
support around the flow_rule infrastructure.
Furthermore, more code can be consolidated by merging
qede_add_cls_rule() and qede_add_tc_flower_fltr(), these two functions
also look very similar.
This driver currently provides simple ACL support, such as 5-tuple
matching, drop policy and queue to CPU.
Drivers that support more features can benefit from this infrastructure
to save even more redundant codebase.

This patch wraps the dissector key and mask - that flower uses to
represent the matching side - around the flow_match structure.
To avoid a follow up patch that would edit the same LoCs in the drivers,
this patch also wraps this new flow match structure around the flow rule
object. This new structure will also contain the flow actions in follow
up patches.
This introduces two new interfaces:
bool flow_rule_match_key(rule, dissector_id)
that returns true if a given matching key is set on, and:
flow_rule_match_XYZ(rule, &match);
To fetch the matching side XYZ into the match container structure, to
retrieve the key and the mask with one single call.

The main motive of this patch is to lay down driver's
tc offload infrastructure in place.
With these changes tc can offload various supported flow
profiles (4 tuples, src-ip, dst-ip, l4 port) for the drop
action. Dropped flows statistic is a global counter for
all the offloaded flows for drop action and is populated
in ethtool statistics as common "gft_filter_drop".
Examples -
tc qdisc add dev p4p1 ingress
tc filter add dev p4p1 protocol ipv4 parent ffff: flower \
skip_sw ip_proto tcp dst_ip 192.168.40.200 action drop
tc filter add dev p4p1 protocol ipv4 parent ffff: flower \
skip_sw ip_proto udp src_ip 192.168.40.100 action drop
tc filter add dev p4p1 protocol ipv4 parent ffff: flower \
skip_sw ip_proto tcp src_ip 192.168.40.100 dst_ip 192.168.40.200 \

prog_attached of struct netdev_bpf should have been superseded
by simply setting prog_id long time ago, but we kept it around
to allow offloading drivers to communicate attachment mode (drv
vs hw). Subsequently drivers were also allowed to report back
attachment flags (prog_flags), and since nowadays only programs
attached will XDP_FLAGS_HW_MODE can get offloaded, we can tell
the attachment mode from the flags driver reports. Remove
prog_attached member.

The vzalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:
vzalloc(a * b)
with:
vzalloc(array_size(a, b))
as well as handling cases of:
vzalloc(a * b * c)
with:
vzalloc(array3_size(a, b, c))
This does, however, attempt to ignore constant size factors like:
vzalloc(4 * 1024)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

With the supported classification modes [4 tuples based,
udp port based, src-ip based], flows can be classified
to the VFs as well. With this patch, flows can be re-directed
to the requested VF provided in "action" field of command.
Please note that driver doesn't really care about the queue bits
in "action" field for the VFs. Since queue will be still chosen
by FW using RSS hash. [I.e., the classification would be done
according to vport-only]
For examples -
ethtool -N p5p1 flow-type udp4 dst-port 8000 action 0x100000000
ethtool -N p5p1 flow-type tcp4 src-ip 192.16.6.10 action 0x200000000

Currently, driver supports flow classification to PF
receive queues based on TCP/UDP 4 tuples [src_ip, dst_ip,
src_port, dst_port] only.
This patch enables to configure different flow profiles
[For example - only UDP dest port or src_ip based] on the
adapter so that classification can be done according to
just those fields as well. Although, at a time just one
type of flow configuration is supported due to limited
number of flow profiles available on the device.
For example -
ethtool -N enp7s0f0 flow-type udp4 dst-port 45762 action 2
ethtool -N enp7s0f0 flow-type tcp4 src-ip 192.16.4.10 action 1

This patch simplifies the ethtool rx flow configuration
[via ethtool -U/-N] flow code base by dividing it logically
into various APIs based on given protocols. It also separates
various validations and calculations done along the flow
in their own APIs.

There may be a need for VF driver to request PF to explicitly update its
bulletin with a MAC address.
e.g. When user assigns a MAC address to VF while VF is still down,
and PF's bulletin board contains different MAC address, in this case,
when VF's interface is brought up, it gets loaded with MAC address from
bulletin board which is not desirable.
To handle this corner case, we need a new TLV to request PF to update
its bulletin board with suggested MAC.
This request will be honored only for trusted VFs.

As per existing behavior, when PF sets a MAC address for a VF
(also called as forced MAC), VF is not allowed to change its
MAC address afterwards.
This puts the limitation on few use cases such as bonding of VFs,
where bonding driver asks VF to change its MAC address.
This patch uses a VF trust mode to allow VF to change its MAC address
in spite PF has set a forced MAC for that VF.

Advance the qed* drivers to use firmware 8.33.1.0:
Modify core driver (qed) to utilize the new FW and initialize the device
with it. This is the lion's share of the patch, and includes changes to FW
interface files, device initialization flows, FW interaction flows, and
debug collection flows.
Modify Ethernet driver (qede) to make use of new FW in fastpath.
Modify RoCE/iWARP driver (qedr) to make use of new FW in fastpath.
Modify FCoE driver (qedf) to make use of new FW in fastpath.
Modify iSCSI driver (qedi) to make use of new FW in fastpath.

Advertise NETIF_F_GRO_HW and set edev->gro_disable according to the
feature flag. Add qede_fix_features() to drop NETIF_F_GRO_HW if
XDP is running or MTU does not support GRO_HW or GRO is not set.
qede_change_mtu() also checks and disables GRO_HW if MTU is not
supported.

ndo_xdp is a control path callback for setting up XDP in the
driver. We can reuse it for other forms of communication
between the eBPF stack and the drivers. Rename the callback
and associated structures and definitions.

Driver maintains its primary MAC in a private field which
gets updated when ndo_dev_set_mac() gets called.
However, there are flows where the primary MAC of the device can change
without said NDO being called [bond device in TLB mode configuring
slaves' addresses], resulting in a configuration where there's a mismatch
between what's apparent to user [the netdevice's value] and what's
configured in the HW [the private value].
As we don't have any real motivation of maintaining this
private field, simply remove it and start using the netdevice's
field instead.

PFs and VFs share the same structure of NDOs today,
and the VFs explicitly fails the ndo_xdp() callback stating
it doesn't support XDP.
This results in lots of:
[qede_xdp:1032(enp131s2)]VFs don't support XDP
------------[ cut here ]------------
WARNING: CPU: 4 PID: 1426 at net/core/rtnetlink.c:1637 rtnl_dump_ifinfo+0x354/0x3c0
...
Call Trace:

...
As every dump request for the VF interface info would fail due to
rtnl_xdp_fill() returning an error code.
To resolve this, introduce a subset of the NDOs meant for the VF
in a seperate structure and register that one instead for VFs,
and omit the ndo_xdp initialization.

In case an XDP program is attached, reserve XDP_PACKET_HEADROOM
bytes at the beginning of the packet for the program to play
with.
Modify the XDP logic in the driver to fill-in the missing bits
and re-calculate offsets and length after the program has finished
running to properly reflect the current status of the packet.
We can then go and remove the limitation of not supporting XDP programs
where xdp_adjust_head is set.
