This function derives the base address of the CQE from the CQE size,
and calculates the real CQE context segment in it from the factor
(this is like before). Before this change the code used the factor to
calculate the base address of the CQE as well.
The factor indicates in which segment of the cqe stride the cqe information
is located. For 32-byte strides, the segment is 0, and for 64 byte strides,
the segment is 1 (bytes 32..63). Using the factor was ok as long as we had
only 32 and 64 byte strides. However, with larger strides, the factor is zero,
and so cannot be used to calculate the base of the CQE.
The helper uses the same method of CQE buffer pulling made by all other
components that reads the CQE buffer (mlx4_ib driver and libmlx4).

This feature is intended for archs having cache line larger then 64B.
Since our CQE/EQEs are generally 64B in those systems, HW will write
twice to the same cache line consecutively, causing pipe locks due to
he hazard prevention mechanism. For elements in a cyclic buffer, writes
are consecutive, so entries smaller than a cache line should be
avoided, especially if they are written at a high rate.
Reduce consecutive writes to same cache line in CQs/EQs, by allowing the
driver to increase the distance between entries so that each will reside
in a different cache line. Until the introduction of this feature, there
were two types of CQE/EQE:
1. 32B stride and context in the [0-31] segment
2. 64B stride and context in the [32-63] segment
This feature introduces two additional types:
3. 128B stride and context in the [0-31] segment (128B cache line)
4. 256B stride and context in the [0-31] segment (256B cache line)
Modify the mlx4_core driver to query the device for the CQE/EQE cache
line stride capability and to enable that capability when the host
cache line size is larger than 64 bytes (supported cache lines are
128B and 256B).
The mlx4 IB driver and libmlx4 need not be aware of this change. The PF
context behaviour is changed to require this change in VF drivers
running on such archs.

Secure-host is the general term for the capability of a device
to protect itself and the subnet from malicious host software.
This is achieved by:
1. Not allowing un-trusted entities to access device configuration
registers, directly (through pci_cr or pci_conf) and indirectly
(through MADs).
2. Hiding M_Key from untrusted entities.
3. Preventing the modification of GUID0 by un-trusted entities
4. Not allowing drivers on untrusted hosts to receive nor to transmit
packets over QP0 (SMP Firewall).
The secure-host capability depends on firmware handling all QP0
packets, and not passing these packets up to the driver. Any information
required by the driver for proper operation (e.g., SM lid) is passed
via events generated by the firmware while processing QP0 MADs.
Driver support mainly requires using the MAD_DEMUX FW command at startup,
where the feature is enabled/disabled through a procedure described in
the Mellanox HCA tools package.

In preparation for a new mlx5 device which is VPI (i.e., ports can be
either IB or ETH), move the pci device functionality from mlx5_ib
to mlx5_core.
This involves the following changes:
1. Move mlx5_core_dev struct out of mlx5_ib_dev. mlx5_core_dev
is now an independent structure maintained by mlx5_core.
mlx5_ib_dev now has a pointer to that struct.
This requires changing a lot of places where the core_dev
struct was accessed via mlx5_ib_dev (now, this needs to
be a pointer dereference).
2. All PCI initializations are now done in mlx5_core. Thus,
it is now mlx5_core which does pci_register_device (and not
mlx5_ib, as was previously).
3. mlx5_ib now registers itself with mlx5_core as an "interface"
driver. This is very similar to the mechanism employed for
the mlx4 (ConnectX) driver. Once the HCA is initialized
(by mlx5_core), it invokes the interface drivers to do
their initializations.
4. There is a new event handler which the core registers:
mlx5_core_event(). This event handler invokes the
event handlers registered by the interfaces.

but current_mac isn't. This leads to inconsistency between current_mac

Fix a regression introduced by commit 35f6f45 ("net/mlx4_en: Don't use
irq_affinity_notifier to track changes in IRQ affinity map").
When core is started in legacy EQ's (number of IRQ's < rx rings), cq->irq_desc
was NULL. This caused a kernel crash under heavy traffic - when having more
than rx NAPI budget completions.
Fixed to have it set for both EQ modes.

In B0 steering mode if promiscuous QP asks to be detached from MCG entry,
and it is the only one in this entry then the entry will never be deleted.
This is a wrong behavior since we don't want to keep those entries after
the promiscuous QP becomes non-promiscuous. Therefore remove steering
entry containing only promiscuous QP.

In current situation host is adding the promiscuous QP to all steering
entries and the default entry as well. In this case when having PV
and SR-IOV on the same setup bridge will receive all traffic that is
targeted to the other VMs. This is bad.
Solution: In SR-IOV mode host can add promiscuous QP to default entry only.
The above problem and fix are relevant for B0 steering mode only.

To make sure that the array index isn't used in the code with
negative value, we stop using the for loop integer iterator
outside of it.
>From now on use members count to swap the last QP with removed one.
Fix also the second occurrence of this flow in mlx4_qp_detach_common().
In mlx4_qp_detach_common() use members_count instead of
loop iterator outside of the for loop.

When removing multicast address in B0 steering mode there is
a bug in cases where there is a single QP registered for the address,
and this QP is also promiscuous. In such cases the entry wouldn't be
deleted from the SW structure representing all Ethernet MCG entries,
but would be removed in HW. This way when driver goes to remove it
from SW and HW structures the HW deletion fails.
Moreover the same index could later be used for registering
different address, which can be Infiniband.

Napi id was not marked for gro_skb, this will lead rx busy loop won't
work correctly since they stack never try to call low latency receive
method because of a zero socket napi id. Fix this by marking napi id
for gro_skb.

In mlx5_core_destroy_mkey(), we must first remove the mr from the
radix tree and then destroy it. Otherwise we might hit a race if the
key was reallocated and we attempted to insert it to the radix tree.
Also handle radix tree insert/delete failures.

It is recommended that TX work not count against the quota.
The cost of TX packet liberation is a minute percentage of what it costs to
process an RX frame. Furthermore, that SKB freeing makes memory available for
other paths in the stack.
Give the TX a larger budget and be more aggressive about cleaning up the Tx
descriptors this budget could be changed using ethtool:
$ ethtool -C eth1 tx-frames-irq <budget>

In 40GE we can't use the default bw units for set ratelimit (100 Mbps)
since the max is 255*100 Mbps = 25 Gbps (not suited for 40GE), thus we need 1 Gbps units.
But for 10GE 1 Gbps units might be too bruit so we use the following solution.
For user set ratelimit <= 25 Gbps:
use 100 Mbps units * user_ratelimit (* 10).
For user set ratelimit > 25 Gbps:
use 1 Gbps units * user_ratelimit.
For user set unlimited ratelimit (0 Gbps):
use 1 Gbps units * MAX_RATELIMIT_DEFAULT (57)
Note: any value > 58 will damage the FW ratelimit computation, so we allow
a max and any higher value will be pulled down to 57.
