Enable mlx5 IPoIB acceleration by declaring
mlx5_ib_{alloc,free}_rdma_netdev and assigning the mlx5
IPoIB rdma_netdev callbacks.
In addition, this patch brings in sync mlx5's IPoIB parts for net and IB
trees. As a precaution, we disabled IPoIB acceleration by default (in
the mlx5_core Kconfig file).

This patch adds support to query the congestion related hardware counters
through new command and links them with other hw counters being available
in hw_counters sysfs location.
In order to reuse existing infrastructure it renames related q_counter
data structures to more generic counters to reflect q_counters and
congestion counters and maybe some other counters in the future.
New hardware counters:
* rp_cnp_handled - CNP packets handled by the reaction point
* rp_cnp_ignored - CNP packets ignored by the reaction point
* np_cnp_sent - CNP packets sent by notification point to respond to
CE marked RoCE packets
* np_ecn_marked_roce_packets - CE marked RoCE packets received by
notification point
It also avoids returning ENOSYS which is specific for invalid
system call and produces the following checkpatch.pl warning.
WARNING: ENOSYS means 'invalid syscall nr' and nothing else

This change adds the ability for flow steering to classify IPv4/6
packets with MPLS tag (Ethertype 0x8847 and 0x8848) as standard IP
packets and hit IPv4/6 classifed steering rules.
When user added a flow rule with IP classification, driver was
implicitly adding ethertype matching to the created rule in order
to distinguish between IPv4 and IPv6 protocols.
Since IP packets with MPLS tag header have MPLS ethertype, they missed
the rule and ended up hitting the default filters.
Such behavior prevented from MPLS packets to undergo inbound traffic
load balancing flows (if such were defined by configuring RSS) to
achieve higher throughput - the way that non-MPLS IP packets performed.
Since our device is able to look past the MPLS tag and identify the
next protocol we introduce this solution which replaces Ethertype
matching by the device's capability to perform IP version parsing
and matching in order to distinguish between IPv4 and IPv6.
Therefore, whenever a flow with IP spec is added and device support IP
version matching, driver will implicitly add IP version matching to the
rule (Based on the IP spec type) without Ethertype matching which will
cause relevant MPLS tagged packets to hit this rule as well.
Otherwise (device doesn't support IP version matching), we fall back to
setting Ethertype matching.
If the user's filters specify an L2 ethertype and an IP spec
the rule will then match both the ethertype and the IP version.
The device's support for IP version matching is reported by the
device via dedicated capability bit in query_device_cap and named
outer/inner_ip_version.

This change fixes an incomplete validation of the user's
flow attributes list.
Previous implementation validated only matching of IPv4 Ethertype
to IPv4 spec of outer headers (in case both Ethernet with specified
Ethertype and IP specs were present) and lacked the validation of:
1. Matching of IPv6 Ethertype in Ethernet spec (if such exists) to an
IPv6 protocol spec (if such exists).
2. Validation of Ethertype to IP protocol matching on inner headers specs.
Which could cause some combinations of unmatching Ethernet and IP
protocols to pass validation and apply on the device.
The fix adds validation of IPv6 Ethertype and IP spec as well as
performing the scan on both outer and inner attributes.

When the "ib_virt" cap is set, configuration of port capabilities need
to be done through mlx5_core_modify_hca_vport_context.
Since modify_hca_vport_context accepts mask and value, there is no need
to read the port capabilities and calculate the new cap values so we
avoid the mutex when ib_virt is set.

Change the drivers to call ib_query_port in their get port
immutable handler instead of their own query port handler.
Doing this required to set the core cap flags of this device
before the ib_query_port call is made, since the IB core might
need these caps to serve the port query.
Drivers are ensured by the IB core that the port attributes passed
to the port query verb implementation are zero, and hence we
removed the zeroing from the drivers.
This patch doesn't add any new functionality.

For some mlx5 HW models (CX4, CX4Lx), the VF driver needs to put part
of the packet headers on the TX descriptor so the e-switch can do proper
matching and steering. This is called "min-inline", it's advertized to
the VF by the FW and also enforced on them by the HW, such that if they
don't obey, their packets are dropped.
SRIOV VF libmlx5 instances should take into account the min-inline
value of their vports. For that end, we provide this value through
the vendor response part of init_ucontext command.
The min inline value is reported in a way which will let newer libmlx5
instances realize that they are running over an older kernel and act
accordingly (e.g apply some educated guess).

Current check requests that new fields in struct
mlx5_ib_alloc_ucontext_req_v2 that are not known to the driver be zero.
This was introduced so new libraries passing additional information to
the kernel through struct mlx5_ib_alloc_ucontext_req_v2 will be notified
by old kernels that do not support their request by failing the
operation. This schecme is problematic since it requires libmlx5 to issue
the requests with descending input size for struct
mlx5_ib_alloc_ucontext_req_v2.
To avoid this, we require that new features that will obey the following
rules:
If the feature requires one or more fields in the response and the at
least one of the fields can be encoded such that a zero value means the
kernel ignored the request then this field will provide the indication
to the library. If no response is required or if zero is a valid
response, a new field should be added that indicates to the library
whether its request was processed.

- Add MODIFY_QP_EX CMD to extend modify_qp.
- Rate limit will be updated in the following state transactions: RTR2RTS,
RTS2RTS. The limit will be removed when SQ is in RST and ERR state.

Enable mlx5 based hardware to report packet pacing capabilities
from kernel to user space. Packet pacing allows to limit the rate to any
number between the maximum and minimum, based on user settings.
The capabilities are exposed to user space through query_device by uhw.
The following capabilities are reported:
1. The maximum and minimum rate limit in kbps supported by packet pacing.
2. Bitmap showing which QP types are supported by packet pacing operation.

On some environments, such as certain SRIOV VF configurations, RoCE is
not supported for mlx5 Ethernet ports. Currently, the driver will not
open IB device on that port.
This is problematic, since we do want user-space RAW Ethernet (RAW_PACKET
QPs) functionality to remain in place. For that end, enhance the relevant
driver flows such that we do create a device instance in that case.

This is a pre-step towards having mlx5 IB device also over Eth ports where
RoCE is not supported. We change the roce enable/disable and roce_lag
init/fini function names to have _eth instead of _roce.
This patch doesn't change any functionality.

Refactor the netdev notifier registration into a small helper function.
This is a pre-step towards having mlx5 IB device over an Ethernet port
which doesn't support RoCE. Also, renamed the de-registration helper
and the new helper as netdev notifier and not roce, to make it clear
this is not only used with roce.
This patch doesn't change any functionality.

Add support to match packet fields which are tunneled,
i.e. support matching the header of the inner packet which is the result of
or bit operation of the original header and the IB_FLOW_SPEC_INNER type.
The combination of IB_FLOW_SPEC_INNER | IB_FLOW_SPEC_VXLAN_TUNNEL is not
needed to be checked, because the IB core has this check already.
