The definition of qib_rc_rnr_retry() has been removed since
commit b4238e70579c ("IB/qib: Use new rdmavt timers"). Also, the definition
of mr_rcu_callback() has been remove since commit 7c2e11fe2dbe ("IB/qib:
Remove qp and mr functionality from qib"). So, let's remove the unused
declartions.

Current code uses many different types when dealing with a port of a RDMA
device: u8, unsigned int and u32. Switch to u32 to clean up the logic.
This allows us to make (at least) the core view consistent and use the
same type. Unfortunately not all places can be converted. Many uverbs
functions expect port to be u8 so keep those places in order not to break
UAPIs. HW/Spec defined values must also not be changed.
With the switch to u32 we now can support devices with more than 255
ports. U32_MAX is reserved to make control logic a bit easier to deal
with. As a device with U32_MAX ports probably isn't going to happen any
time soon this seems like a non issue.
When a device with more than 255 ports is created uverbs will report the
RDMA device as having 255 ports as this is the max currently supported.
The verbs interface is not changed yet because the IBTA spec limits the
port size in too many places to be u8 and all applications that relies in
verbs won't be able to cope with this change. At this stage, we are
extending the interfaces that are using vendor channel solely
Once the limitation is lifted mlx5 in switchdev mode will be able to have
thousands of SFs created by the device. As the only instance of an RDMA
device that reports more than 255 ports will be a representor device and
it exposes itself as a RAW Ethernet only device CM/MAD/IPoIB and other
ULPs aren't effected by this change and their sysfs/interfaces that are
exposes to userspace can remain unchanged.
While here cleanup some alignment issues and remove unneeded sanity
checks (mainly in rdmavt),

The currently include file ordering for rdmavt headers has an
ab/ba include issue the precludes using inlines from rdma_vt.h
in rdmavt_qp.h.
At the heart of the issue is that rdma_vt.h includes rdmavt_qp.h.
Fix the ordering issue by adjusting rdma_vt.h to not require rdmavt_qp.h
and move qp related inlines to rdmavt_qp.h.
Additionally, promote rvt_mmap_info to rdma_vt.h since it is shared
by rdmavt_cq.h and rdmavt_qp.h.

This patch moves hfi1_copy_sge() into rdmavt for sharing with qib.
This patch also moves all the wss_*() functions into rdmavt as
several wss_*() functions are called from hfi1_copy_sge()
When SGE copy mode is adaptive, cacheless copy may be done in some cases
for performance reasons. In those cases, X86 cacheless copy function
is called since the drivers that use rdmavt and may set SGE copy mode
to adaptive are X86 only. For this reason, this patch adds
"depends on X86_64" to rdmavt/Kconfig.

Current implementation allows each qp to have only one send engine. As
such, each qp has only one list to queue prebuilt packets when send engine
resources are not available. To improve performance, it is desired to
support multiple send engines for each qp.
This patch creates the framework to support two send engines
(two legs) for each qp for the TID RDMA protocol, which can be easily
extended to support more send engines. It achieves the goal by creating a
leg specific struct, iowait_work in the iowait struct, to hold the
work_struct and the tx_list as well as a pointer to the parent iowait
struct.
The hfi1_pkt_state now has an additional field to record the current legs
work structure and that is now passed to all egress waiters to determine
the leg that needs to wait via a new iowait helper. The APIs are adjusted
to use the new leg specific struct as required.
Many new and modified helpers are added to support this change.

The post_send() path determines if it should post directly or, schedule
the post for later. The current logic is:
if the swqe ring is empty or (for hfi1) wqe->length <= piothreshold
post the send
else
schedule
This can allow large requests to call the send engine directly. Large
requests can potentially produce a large number of packets prior to
returning to the caller, blocking the caller from posting more requests,
and allowing better parallel processing.
Allow the driver(s) more say in this logic (pass call_send to the driver,
rather than examining a return value).
Update hfi1/qib logic to schedule the send engine if an RC or UC message
is larger than the QP MTU size.

The internal flag IP_BASED_GIDS was added to a field that was being used
to hold the port Info CapabilityMask without considering the effects this
will have. Since most drivers just use the value from the HW MAD it means
IP_BASED_GIDS will also become set on any HW that sets the IBA flag
IsOtherLocalChangesNoticeSupported - which is not intended.
Fix this by keeping port_cap_flags only for the IBA CapabilityMask value
and store unrelated flags externally. Move the bit definitions for this to
ib_mad.h to make it clear what is happening.
To keep the uAPI unchanged define a new set of flags in the uapi header
that are only used by ib_uverbs_query_port_resp.port_cap_flags which match
the current flags supported in rdma-core, and the values exposed by the
current kernel.

This patch adds an additional lock to reduce contention on the s_lock.
This lock is used in post_send() so that the post_send is not
serialized with the send engine and other send related processing.
To do this the s_next_psn is now maintained on post_send() while
post_send() related fields are moved to a new cache line. There is
an s_avail maintained for the post_send() to mitigate trading cache
lines with the send engine. The lock is released/acquired around
releasing the just built packet to the egress mechanism.
