Test the PTP Physical Hardware Clock functionality using the "phc_ctl" (a
part of "linuxptp").
The test contains three sub-tests:
* "settime" test
* "adjtime" test
* "adjfreq" test
"settime" test:
* set the PHC time to 0 seconds.
* wait for 120.5 seconds.
* check if PHC time equal to 120.XX seconds.
"adjtime" test:
* set the PHC time to 0 seconds.
* adjust the time by 10 seconds.
* check if PHC time equal to 10.XX seconds.
"adjfreq" test:
* adjust the PHC frequency to be 1% faster.
* set the PHC time to 0 seconds.
* wait for 100.5 seconds.
* check if PHC time equal to 101.XX seconds.
Usage:
$ ./phc.sh /dev/ptp<X>
It is possible to run a subset of the tests, for example:
* To run only the "settime" test:
$ TESTS="settime" ./phc.sh /dev/ptp<X>

Adding delays to TCP flows is crucial for studying behavior
of TCP stacks, including congestion control modules.
Linux offers netem module, but it has unpractical constraints :
- Need root access to change qdisc
- Hard to setup on egress if combined with non trivial qdisc like FQ
- Single delay for all flows.
EDT (Earliest Departure Time) adoption in TCP stack allows us
to enable a per socket delay at a very small cost.
Networking tools can now establish thousands of flows, each of them
with a different delay, simulating real world conditions.
This requires FQ packet scheduler or a EDT-enabled NIC.
This patchs adds TCP_TX_DELAY socket option, to set a delay in
usec units.
unsigned int tx_delay = 10000; /* 10 msec */
setsockopt(fd, SOL_TCP, TCP_TX_DELAY, &tx_delay, sizeof(tx_delay));
Note that FQ packet scheduler limits might need some tweaking :
man tc-fq
PARAMETERS
limit
Hard limit on the real queue size. When this limit is
reached, new packets are dropped. If the value is lowered,
packets are dropped so that the new limit is met. Default
is 10000 packets.
flow_limit
Hard limit on the maximum number of packets queued per
flow. Default value is 100.
Use of TCP_TX_DELAY option will increase number of skbs in FQ qdisc,
so packets would be dropped if any of the previous limit is hit.
Use of a jump label makes this support runtime-free, for hosts
never using the option.
Also note that TSQ (TCP Small Queues) limits are slightly changed
with this patch : we need to account that skbs artificially delayed
wont stop us providind more skbs to feed the pipe (netem uses
skb_orphan_partial() for this purpose, but FQ can not use this trick)
Because of that, using big delays might very well trigger
old bugs in TSO auto defer logic and/or sndbuf limited detection.

If there is not enough memory to allocate io queues the driver will
try to allocate smaller queues.
The backoff algorithm is as follows:
1. Try to allocate TX and RX and if successful.
1.1. return success
2. Divide by 2 the size of the larger of RX and TX queues (or both if their size is the same).
3. If TX or RX is smaller than 256
3.1. return failure.
4. else
4.1. go back to 1.
Also change the tx_queue_size, rx_queue_size field names in struct
adapter to requested_tx_queue_size and requested_rx_queue_size, and
use RX and TX queue 0 for actual queue sizes.
Explanation:
The original fields were useless as they were simply used to assign
values once from them to each of the queues in the adapter in ena_probe().
They could simply be deleted. However now that we have a backoff
feature, we have use for them. In case of backoff there is a difference
between the requested queue sizes and the actual sizes. Therefore there
is a need to save the requested queue size for future retries of queue
allocation (for example if allocation failed and then ifdown + ifup was
called we want to start the allocation from the original requested size of
the queues).

tls: add support for kernel-driven resync and nfp RX offload
This series adds TLS RX offload for NFP and completes the offload
by providing resync strategies. When TLS data stream looses segments
or experiences reorder NIC can no longer perform in line offload.
Resyncs provide information about placement of records in the
stream so that offload can resume.
Existing TLS resync mechanisms are not a great fit for the NFP.
In particular the TX resync is hard to implement for packet-centric
NICs. This patchset adds an ability to perform TX resync in a way
similar to the way initial sync is done - by calling down to the
driver when new record is created after driver indicated sync had
been lost.
Similarly on the RX side, we try to wait for a gap in the stream
and send record information for the next record. This works very
well for RPC workloads which are the primary focus at this time.

TLS offload drivers keep track of TCP seq numbers to make sure
the packets are fed into the HW in order.
When packets get dropped on the way through the stack, the driver
will get out of sync and have to use fallback encryption, but unless
TCP seq number is resynced it will never match the packets correctly
(or even worse - use incorrect record sequence number after TCP seq
wraps).
Existing drivers (mlx5) feed the entire record on every out-of-order
event, allowing FW/HW to always be in sync.
This patch adds an alternative, more akin to the RX resync. When
driver sees a frame which is past its expected sequence number the
stream must have gotten out of order (if the sequence number is
smaller than expected its likely a retransmission which doesn't
require resync). Driver will ask the stack to perform TX sync
before it submits the next full record, and fall back to software
crypto until stack has performed the sync.

TLS offload device may lose sync with the TCP stream if packets
arrive out of order. Drivers can currently request a resync at
a specific TCP sequence number. When a record is found starting
at that sequence number kernel will inform the device of the
corresponding record number.
This requires the device to constantly scan the stream for a
known pattern (constant bytes of the header) after sync is lost.
This patch adds an alternative approach which is entirely under
the control of the kernel. Kernel tracks records it had to fully
decrypt, even though TLS socket is in TLS_HW mode. If multiple
records did not have any decrypted parts - it's a pretty strong
indication that the device is out of sync.
We choose the min number of fully encrypted records to be 2,
which should hopefully be more than will get retransmitted at
a time.
After kernel decides the device is out of sync it schedules a
resync request. If the TCP socket is empty the resync gets
performed immediately. If socket is not empty we leave the
record parser to resync when next record comes.
Before resync in message parser we peek at the TCP socket and
don't attempt the sync if the socket already has some of the
next record queued.
On resync failure (encrypted data continues to flow in) we
retry with exponential backoff, up to once every 128 records
(with a 16k record thats at most once every 2M of data).
