Transmitted packet timestamping accuracy can be improved when using
timestamp from the port, instead of packet CQE creation timestamp, as
it better reflects the actual time of a packet's transmit.
TX port timestamping is supported starting from ConnectX6-DX hardware.
Although at the original completion, only CQE timestamp can be attached,
we are able to get TX port timestamping via an additional completion over
a special CQ associated with the SQ (in addition to the regular CQ).
Driver to ignore the original packet completion timestamp, and report
back the timestamp of the special CQ completion. If the absolute timestamp
diff between the two completions is greater than 1 / 128 second, ignore
the TX port timestamp as it has a jitter which is too big.
No skb will be generate out of the extra completion.
Allocate additional CQ per ptpsq, to receive the TX port timestamp.
Driver to hold an skb FIFO in order to map between transmitted skb to
the two expected completions. When using ptpsq, hold double refcount on
the skb, to gaurantee it will not get released before both completions
arrive.
Expose dedicated counters of the ptp additional CQ and connect it to the
TX health reporter.
This patch improves TX Hardware timestamping offset to be less than 40ns
at a 100Gbps line rate, compared to 600ns before.
With that, making our HW compliant with G.8273.2 class C, and allow Linux
systems to be deployed in the 5G telco edge, where this standard is a
must.

Add TX PTP port object support for better TX timestamping accuracy.
Currently, driver supports CQE based TX port timestamp. Device
also offers TX port timestamp, which has less jitter and better
reflects the actual time of a packet's transmit.
Define new driver layout called ptpsq, on which driver will create
SQs that will support TX port timestamp for their transmitted packets.
Driver to identify PTP TX skbs and steer them to these dedicated SQs
as part of the select queue ndo.
Driver to hold ptpsq per TC and report them at
netif_set_real_num_tx_queues().
Add support for all needed functionality in order to xmit and poll
completions received via ptpsq.

When qeth_qdio_handle_aob() frees dangling allocations in the notified
TX buffer, there are rare tear-down cases where
qeth_drain_output_queue() would later call qeth_clear_output_buffer()
for the same buffer - and thus end up walking the buffer a second time
to check for dangling kmem_cache allocations.
Luckily current code previously scrubs such a buffer, so
qeth_clear_output_buffer() would find buf->buffer->element[i].addr as
NULL and not do anything. But this is fragile, and we can easily improve
it by consistently clearing the ->is_header flag after freeing the
allocation.

For TX buffers that require an additional async notification via QAOB, the
TX completion code can now manage all the necessary processing if the
notification has already occurred (or is occurring concurrently).
In such cases we can avoid replacing the metadata that is associated
with the buffer's slot on the ring, and just keep using the current one.
As qeth_clear_output_buffer() will also handle any kmem cache-allocated
memory that was mapped into the TX buffer, qeth_qdio_handle_aob()
doesn't need to worry about it.
While at it, also remove the unneeded forward declaration for
qeth_init_qdio_out_buf().

All qeth devices have a minimum set of sysfs attributes, and non-OSN
devices share a group of additional attributes. Depending on whether
the device is forced to use a specific discipline, the device_type then
specifies further attributes.
Shift the common attributes into dev->groups, so that the device_type
only contains the discipline-specific attributes. This avoids exposing
the common attributes to the disciplines, and nicely cleans up our
sysfs code.
While replacing the qeth_l*_*_device_attributes() helpers, switch from

Perf. optimizations for TCP Recv. Zerocopy
This patchset contains several optimizations for TCP Recv. Zerocopy.
Summarized:
1. It is possible that a read payload is not exactly page aligned -
that there may exist "straggler" bytes that we cannot map into the
caller's address space cleanly. For this, we allow the caller to
provide as argument a "hybrid copy buffer", turning
getsockopt(TCP_ZEROCOPY_RECEIVE) into a "hybrid" operation that allows
the caller to avoid a subsequent recvmsg() call to read the
stragglers.
2. Similarly, for "small" read payloads that are either below the size
of a page, or small enough that remapping pages is not a performance
win - we allow the user to short-circuit the remapping operations
entirely and simply copy into the buffer provided.
Some of the patches in the middle of this set are refactors to support
this "short-circuiting" optimization.
3. We allow the user to provide a hint that performing a page zap
operation (and the accompanying TLB shootdown) may not be necessary,
for the provided region that the kernel will attempt to map pages
into. This allows us to avoid this expensive operation while holding
the socket lock, which provides a significant performance advantage.
With all of these changes combined, "medium" sized receive traffic
(multiple tens to few hundreds of KB) see significant efficiency gains
when using TCP receive zerocopy instead of regular recvmsg(). For
example, with RPC-style traffic with 32KB messages, there is a roughly
15% efficiency improvement when using zerocopy. Without these changes,
there is a roughly 60-70% efficiency reduction with such messages when
employing zerocopy.

Zapping pages is required only if we are calling vm_insert_page into a
region where pages had previously been mapped. Receive zerocopy allows
reusing such regions, and hitherto called zap_page_range() before
calling vm_insert_page() in that range.
zap_page_range() can also be triggered from userspace with
madvise(MADV_DONTNEED). If userspace is configured to call this before
reusing a segment, or if there was nothing mapped at this virtual
address to begin with, we can avoid calling zap_page_range() under the
socket lock. That said, if userspace does not do that, then we are
still responsible for calling zap_page_range().
This patch adds a flag that the user can use to hint to the kernel
that a zap is not required. If the flag is not set, or if an older
user application does not have a flags field at all, then the kernel
calls zap_page_range as before. Also, if the flag is set but a zap is
still required, the kernel performs that zap as necessary. Thus
incorrectly indicating that a zap can be avoided does not change the
correctness of operation. It also increases the batchsize for
vm_insert_pages and prefetches the page struct for the batch since
we're about to bump the refcount.
An alternative mechanism could be to not have a flag, assume by
default a zap is not needed, and fall back to zapping if needed.
However, this would harm performance for older applications for which
a zap is necessary, and thus we implement it with an explicit flag
so newer applications can opt in.
When using RPC-style traffic with medium sized (tens of KB) RPCs, this
change yields an efficency improvement of about 30% for QPS/CPU usage.
