The SRP initiator allows to set max_sectors to a value that exceeds
the largest amount of data that can be mapped at once with an mlx4
HCA using fast registration and a page size of 4 KB. Hence modify
ib_map_mr_sg() such that it can map partial sg-elements. If an
sg-element has been mapped partially, let the caller know
which fraction has been mapped by adjusting *sg_offset.

This patch adds support to create RoCE-v2 compatible AH. It uses ahid
field to tell network-header-type to user space library. The library
has to decode network-header-type from ahid field.

This patch implements following changes to support RoCE-v2
in the RC path:
* Get the GID-type for a given sgid.
* Based on the GID-type get IPv4/IPv6 L3-address
and give those to underlying device.
* Resolve and provide network header type to device.

This patch adds following changes to support RoCE-v2

* During AH creation GID-type is resolved for a given gid-index.

Today ocrdma driver defer arming the CQ till poll is called.
This was used to prevent calling poll-cq on an armed CQ.
Recently a set of new CQ API has been introduced into the linux
kernel. The implementation of this API guarantees that a given
CQ is never armed before calling poll on it. Most of the kernel
ULPs have already moved to use this new API or have a code where
poll is called before arming the CQ.
Thus, the above workaround in ocrdma is not needed anymore.
This patch removes the additional logic to deffer arm till poll
is called. This patch adds a simple scheme where ib_req_notify_cq()
will actually arm the cq.

In the latest kernel, process_mad hook of the driver can be invoked as
soon as device is registered. In this hook, ocrdma driver is issuing a
command to get the stats counters from the HW. This is triggering system

Recently Dough Ledford reported a deadlock happening
between ocrdma-load sequence and NetworkManager service
issuing "open" on be2net interface.
The deadlock happens when any be2net hook (e.g. open/close) is called
in parallel to insmod ocrdma.ko.
A. be2net is sending administrative open/close event to ocrdma holding
device_list_mutex. It does this from ndo_open/ndo_stop hooks of be2net.
So sequence of locks is rtnl_lock---> device_list lock
B. When new ocrdma roce device gets registered, infiniband stack now
takes rtnl_lock in ib_register_device() in GID initialization routines.
So sequence of locks in this path is device_list lock ---> rtnl_lock.
This improper locking sequence causes deadlock.
With this patch we stop using administrative open and close events
injected by be2net driver. These events were used to dispatch PORT_ACTIVE
and PORT_ERROR events to the IB-stack. This patch implements a logic
to receive async-link-events generated from CNA whenever link-state-change
is detected. Now on, these async-events will be used to dispatch
PORT_ACTIVE and PORT_ERROR events to IB-stack.
Depending on async-events from CNA removes the need to hold device-list-mutex
and thus breaks the busy-wait scenario.

Support the new memory registration API by allocating a
private page list array in ocrdma_mr and populate it when
ocrdma_map_mr_sg is invoked. Also, support IB_WR_REG_MR
by duplicating IB_WR_FAST_REG_MR, but take the needed
information from different places:
- page_size, iova, length, access flags (ib_mr)
- page array (ocrdma_mr)
- key (ib_reg_wr)
The IB_WR_FAST_REG_MR handlers will be removed later when
all the ULPs will be converted.

This patch split up struct ib_send_wr so that all non-trivial verbs
use their own structure which embedds struct ib_send_wr. This dramaticly
shrinks the size of a WR for most common operations:
sizeof(struct ib_send_wr) (old): 96
sizeof(struct ib_send_wr): 48
sizeof(struct ib_rdma_wr): 64
sizeof(struct ib_atomic_wr): 96
sizeof(struct ib_ud_wr): 88
sizeof(struct ib_fast_reg_wr): 88
sizeof(struct ib_bind_mw_wr): 96
sizeof(struct ib_sig_handover_wr): 80
And with Sagi's pending MR rework the fast registration WR will also be
down to a reasonable size:
sizeof(struct ib_fastreg_wr): 64

Previously, vlan id and source MAC were used from QP attributes. Since
the net device is now stored in the GID attributes, they could be used
instead of getting this information from the QP attributes.
IB_QP_SMAC, IB_QP_ALT_SMAC, IB_QP_VID and IB_QP_ALT_VID were removed
because there is no known libibverbs that uses them.
This commit also modifies the vendors (mlx4, ocrdma) drivers in order

In order to support alternate sized MADs (and variable sized MADs on OPA
devices) add in/out MAD size parameters to the process_mad core call.
In addition, add an out_mad_pkey_index to communicate the pkey index the driver
wishes the MAD stack to use when sending OPA MAD responses.
The out MAD size and the out MAD PKey index are required by the MAD
stack to generate responses on OPA devices.
Furthermore, the in and out MAD parameters are made generic by specifying them
as ib_mad_hdr rather than ib_mad.
Drivers are modified as needed and are protected by BUG_ON flags if the MAD
sizes passed to them is incorrect.

Add max MAD size to the device immutable data set and have all drivers that
support MADs report the current IB MAD size (IB_MGMT_MAD_SIZE) to the core.
Verify MAD size data in both the MAD core and when reading the immutable data.
OPA drivers will report alternate MAD sizes in subsequent patches.

Vendors should be able to pass vendor specific data to/from
user-space via query_device uverb. In order to do this,
we need to pass the vendors' specific udata.

Add a new ib_cq_init_attr structure which contains the
previous cqe (minimum number of CQ entries) and comp_vector
(completion vector) in addition to a new flags field.
All vendors' create_cq callbacks are changed in order
to work with the new API.
This commit does not change any functionality.

A reorganisation of the PD allocation and deallocation in commit
9ba1377daa ("RDMA/ocrdma: Move PD resource management to driver.")
introduced a double free on pd, as detected by static analysis by
smatch:
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:682 ocrdma_alloc_pd()
error: double free of 'pd'^
The original call to ocrdma_mbx_dealloc_pd() (which does not kfree
pd) was replaced with a call to _ocrdma_dealloc_pd() (which does
kfree pd). The kfree following this call causes the double free,
so just remove it to fix the problem.

If ocrdma_get_pd_num() fails, then we need to free the pd struct we allocated.

The process_mad device function declares some parameters as "in". Make those
parameters const and adjust the call tree under process_mad in the various
drivers accordingly.

As of commit 5eb620c81ce3 "IB/core: Add helpers for uncached GID and P_Key
searches"; pkey_tbl_len and gid_tbl_len are immutable data which are stored in
the ib_device.
The per port core capability flags to be added later are also immutable data to
be stored in the ib_device object.
In preparation for this create a structure for per port immutable data and
place the pkey and gid table lengths within this structure.
"get_port_immutable" is added as a mandatory device function to allow the
drivers to fill in this data.
