So far, the PCI BAR0 register is used for triggering FW reset. However,
that is a legacy attitude and it is recommended to use MRSR to perform
reset instead. So do that. Move the reset into init() function as
the cmd interface needs to be used. With that, IRQ initialization needs
to be moved as well. As a side effect, the reset move simplifies
the devlink reload flow.

From: Or Gerlitz <ogerlitz@mellanox.com>
The user will typically set the actions order such that the mirror
port (mirror VF) sees packets as the original port (VF under
mirroring) sent them or as it will receive them. In the general case,
it means that packets are potentially sent to the mirror port before
or after some actions were applied on them.
To properly do that, we follow on the exact action order as set for
the flow and make sure this will also be the case when we program the
HW offload.
If all the actions should apply before forwarding to the mirror and dest port,
mirroring is just multicasting to the two vports. Otherwise, we split
the TC flow to two HW rules, where the 1st applies only the actions
needed up to the mirror (if there are such) and the 2nd the rest of
the actions plus the forwarding to the dest vport.

Move all RQ, SQ and channel counters from the channel objects into the
priv structure. With this change, counters will not be reset upon
channel configuration changes.
Channel's statistics for SQs which are associated with TCs higher than
zero will be presented in ethtool -S, only for SQs which were opened at
least once since the module was loaded (regardless of their open/close
current status). This is done in order to decrease the total amount of
statistics presented and calculated for the common out of box use (no
QoS).
mlx5e_channel_stats is a compound of CH,RQ,SQs stats in order to
create locality for the NAPI when handling TX and RX of the same
channel.
Align the new statistics struct per ring to avoid several channels
update to the same cache line at the same time.

We fill SQ edge with NOPs to avoid WQEs wrap.
Here, instead of doing that in advance for the maximum possible
WQE size, we do it on-demand using the actual WQE size.
We re-order some parts in mlx5e_sq_xmit to finish the calculation
of WQE size (ds_cnt) before doing any writes to the WQE buffer.
When SQ work queue is fragmented (introduced in an downstream patch),
dealing with WQE wraps becomes more frequent. This change would drastically
reduce the overhead in this case.

If a TC rule needs to be split for mirroring, create two HW rules,
in the first level and the second level flow tables accordingly.
In the first level flow table, forward the packet to the mirror
port and forward the packet to the second level flow table for
further processing, eg. encap, vlan push or header re-write.
Currently the matching is repeated in both stages.

Currently, we only support the mirred redirect TC sub-action. In order
to support flow based vport mirroring, add support to parse the mirred
mirror sub-action.
For mirroring, user-space will typically set the action order such that
the mirror port (mirror VF) sees packets as the original port (VF under
mirroring) sent them or as it will receive them.
In the general case, it means that packets are potentially sent to the
mirror port before or after some actions were applied on them. To
properly do that, we should follow on the exact action order as set for
the flow and make sure this will also be the case when we program the HW
offload.
We introduce a counter for the output ports (attr->out_count), which we
increase when parsing each mirred redirect/mirror sub-action and when
dealing with encap.
We introduce a counter (attr->mirror_count) telling us if split is
needed. If no split is needed and mirroring is just multicasting to
vport, the mirror count is zero, all the actions of the TC flow should
apply on that single HW flow.
If split is needed, the mirror count tells where to do the split, all
non-mirred tc actions should apply only after the split.
The mirror count is set while parsing the following actions encap/decap,
header re-write, vlan push/pop.

When a system is under memory presure (high usage with fragments),
the original 256KB ICM chunk allocations will likely trigger kernel
memory management to enter slow path doing memory compact/migration
ops in order to complete high order memory allocations.
When that happens, user processes calling uverb APIs may get stuck
for more than 120s easily even though there are a lot of free pages
in smaller chunks available in the system.
Syslog:
...
Dec 10 09:04:51 slcc03db02 kernel: [397078.572732] INFO: task
oracle_205573_e:205573 blocked for more than 120 seconds.
...
With 4KB ICM chunk size on x86_64 arch, the above issue is fixed.
However in order to support smaller ICM chunk size, we need to fix
another issue in large size kcalloc allocations.
E.g.
Setting log_num_mtt=30 requires 1G mtt entries. With the 4KB ICM chunk
size, each ICM chunk can only hold 512 mtt entries (8 bytes for each mtt
entry). So we need a 16MB allocation for a table->icm pointer array to
hold 2M pointers which can easily cause kcalloc to fail.
The solution is to use kvzalloc to replace kcalloc which will fall back
to vmalloc automatically if kmalloc fails.

The table is the one which originally was added for offloading TC NIC

This scheme breaks when the core TC code calls us to add the same flow
twice, (e.g under egdev use case) since we don't spot that and offload
a 2nd flow into the HW with the wrong source vport.

Next six patches from Roi and Co adds support for merged
sriov e-switch which comes to serve cases where both PFs, VFs set
on them and both uplinks are to be used in single v-switch SW model.
When merged e-switch is supported, the per-port e-switch is logically
merged into one e-switch that spans both physical ports and all the VFs.
This model allows to offload TC eswitch rules between VFs belonging
to different PFs (and hence have different eswitch affinity), it also
sets the some of the foundations needed for uplink LAG support.

The source e-switch owner allows a vport on one e-switch port be associated
with a rule defined on the second port e-switch.
The role of the source eswitch owner valid bit in the flow group is to
allow the firmware fail driver attempts to wild card the source eswitch
match field. If this bit is not set, the firmware ignores the source
eswitch owner field totally.

When creating FTE, properly distinguish between destination being vport
or tir. The previous code just worked accidentally b/c of both dest being
in the same offset within a union.
