Size of pages are held by struct ib_umem in page_size field.

It is better to store it as an exponent, because page size by nature
is always power-of-two and used as a factor, divisor or ilog2's argument.

The conversion of page_size to be page_shift allows to have portable
code and avoid following error while compiling on ARM:

hns_roce_v1_cq_set_ci() calls roce_set_bit() on an uninitialized field,
which will then change only a few of its bits, causing a warning with
the latest gcc:

infiniband/hw/hns/hns_roce_hw_v1.c: In function 'hns_roce_v1_cq_set_ci':
infiniband/hw/hns/hns_roce_hw_v1.c:1854:23: error: 'doorbell[1]' is used uninitialized in this function [-Werror=uninitialized]
  roce_set_bit(doorbell[1], ROCEE_DB_OTHERS_H_ROCEE_DB_OTH_HW_SYNS_S, 1);

The code is actually correct since we always set all bits of the
port_vlan field, but gcc correctly points out that the first
access does contain uninitialized data.

This initializes the field to zero first before setting the
individual bits.

There is a difference when parsing a completion entry between Ethernet
and IB ports. When link layer is Ethernet the bits describe the type of
L3 header in the packet. In the case when link layer is Ethernet and VLAN
header is present the value of SL is equal to the 3 UP bits in the VLAN
header. If VLAN header is not present then the SL is undefined and consumer
of the completion should check if IB_WC_WITH_VLAN is set.

While that, this patch also fills the vlan_id field in the completion if
present.

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

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.

A warning message during SRIOV multicast cleanup should have actually been
a debug level message. The condition generating the warning does no harm
and can fill the message log.

In some cases, during testing, some tests were so intense as to swamp the
message log with these warning messages, causing a stall in the console
message log output task. This stall caused an NMI to be sent to all CPUs
(so that they all dumped their stacks into the message log).
Aside from the message flood causing an NMI, the tests all passed.

Once the message flood which caused the NMI is removed (by reducing the
warning message to debug level), the NMI no longer occurs.

Sample message log (console log) output illustrating the flood and
resultant NMI (snippets with comments and modified with ... instead
of hex digits, to satisfy checkpatch.pl):
