Allow processes that share the same XRC domain to open an existing
shareable QP. This permits those processes to receive events on the
shared QP and transfer ownership, so that any process may modify the
QP. The latter allows the creating process to exit, while a remaining
process can still transition it for path migration purposes.

XRC TGT QPs are shared resources among multiple processes. Since the
creating process may exit, allow other processes which share the same
XRC domain to open an existing QP. This allows us to transfer
ownership of an XRC TGT QP to another process.

Because an XRC TGT QP can end up being shared among multiple
processes, don't have the ib_cm automatically send a DREQ when the
userspace process that owns the ib_cm_id exits. Disconnect can be
initiated by the user directly; otherwise, the owner of the XRC INI QP
controls the connection.
Note that as a result of the process exiting, the ib_cm will stop
tracking the XRC connection on the target side. For the purposes of
disconnecting, this isn't a big deal. The ib_cm will respond to the
DREQ appropriately. For other messages, mainly LAP, the CM will
reject the request, since there's no one available to route the
request to.

Allow the user to indicate the QP type separately from the port space
when allocating an rdma_cm_id. With RDMA_PS_IB, there is no longer a
1:1 relationship between the QP type and port space, so we need to
switch on the QP type to select between UD and connected QPs.

Allow user space to operate on XRC TGT QPs the same way as other types
of QPs, with one notable exception: since XRC TGT QPs may be shared
among multiple processes, the XRC TGT QP is allowed to exist beyond the
lifetime of the creating process.
The process that creates the QP is allowed to destroy it, but if the
process exits without destroying the QP, then the QP will be left bound
to the lifetime of the XRCD.
TGT QPs are not associated with CQs or a PD.

XRC TGT QPs are intended to be shared among multiple users and
processes. Allow the destruction of an XRC TGT QP to be done explicitly
through ib_destroy_qp() or when the XRCD is destroyed.
To support destroying an XRC TGT QP, we need to track TGT QPs with the
XRCD. When the XRCD is destroyed, all tracked XRC TGT QPs are also
cleaned up.
To avoid stale reference issues, if a user is holding a reference on a
TGT QP, we increment a reference count on the QP. The user releases the
reference by calling ib_release_qp. This releases any access to the QP
from a user above verbs, but allows the QP to continue to exist until
destroyed by the XRCD.

XRC ("eXtended reliable connected") is an IB transport that provides
better scalability by allowing senders to specify which shared receive
queue (SRQ) should be used to receive a message, which essentially
allows one transport context (QP connection) to serve multiple
destinations (as long as they share an adapter, of course).
XRC communication is between an initiator (INI) QP and a target (TGT)
QP. Target QPs are associated with SRQs through an XRCD. An XRC TGT QP
behaves like a receive-only RD QP. XRC INI QPs behave similarly to RC
QPs, except that work requests posted to an XRC INI QP must specify the
remote SRQ that is the target of the work request.
We define two new QP types for XRC, to distinguish between INI and TGT
QPs, and update the core layer to support XRC QPs.

queue (SRQ) should be used to receive a message, which essentially
allows one transport context (QP connection) to serve multiple

A few new concepts are introduced to support this. This patch adds:
- A new device capability flag, IB_DEVICE_XRC, which low-level
drivers set to indicate that a device supports XRC.
- A new object type, XRC domains (struct ib_xrcd), and new verbs
ib_alloc_xrcd()/ib_dealloc_xrcd(). XRCDs are used to limit which
XRC SRQs an incoming message can target.

The heavy weight spinlock in qib_lookup_qpn() is replaced with RCU.
The hash list itself is now accessed via jhash functions instead of mod.
The changes should benefit multiple receive contexts in different
processors by not contending for the lock just to read the hash
structures.
The patch also adds a lookaside_qp (pointer) and a lookaside_qpn in
the context. The interrupt handler will test the current packet's qpn
against lookaside_qpn if the lookaside_qp pointer is non-NULL. The
pointer is NULL'ed when the interrupt handler exits.

The memset for zeroing work completions had been unconditional.
This patch removes the memset and moves the zeroing into the work
completion with a more explicit field by field set. With this patch,
non-ONLY/non-LAST packets will avoid the overhead since they will not
generate a completion.

The code that was recently introduced to report the number
of free contexts is flawed for multiple HCAs:
/* Return the number of free user ports (contexts) available. */
return scnprintf(buf, PAGE_SIZE, "%u\n", dd->cfgctxts -
dd->first_user_ctxt - (u32)qib_stats.sps_ctxts);
The qib_stats is global to the module, not per HCA, so the code is broken
for multiple HCAs.
This patch adds a qib_devdata field, freectxts, that reflects the free
contexts for this HCA.

Support for Packed and Unaligned (PAU) FPDUs is needed for
interoperability between NES and non-NES nodes. When the NES hardware
detects a PAU frame, it will pass it to the driver to process the
frame. NES driver creates a new frame for each FPDU and forwards it
to the hardware to be sent to its associated qp.

we even check and yell when an interrupt handler returns with
interrupts enabled -- cf commit b738a50a2026 ("genirq: Warn when
handler enables interrupts").
So now this flag is a no-op and can be removed.
