4c02e453cc eal: introduce SMP memory barriers
This commit introduce rte_smp_mb(), rte_smp_wmb() and rte_smp_rmb(), in
order to enable memory barriers between lcores.
The patch does not provide any functional change for IA, the goal is to
have infrastructure for weakly ordered machines like ARM to work on DPDK.

71f39b07b6 ixgbe: fix Tx hang when RS distance exceeds HW limit
One of the ways to reproduce the issue:

testpmd <EAL-OPTIONS> -- -i --txqflags=0
testpmd> set fwd txonly
testpmd> set txpkts 64,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4
testpmd> set txsplit rand
testpmd> start

After some time TX on ixgbe queue will hang,
and all packet transmission on that queue will stop.

This bug was first reported and investigated by
Vlad Zolotarov <vladz@cloudius-systems.com>:
"We can reproduce this issue when stressed the xmit path with a lot of highly
fragmented TCP frames (packets with up to 33 fragments with non-headers
fragments as small as 4 bytes) with all offload features enabled."

The root cause is that ixgbe_xmit_pkts() in some cases violates the HW rule
that the distance between TDs with RS bit set should not exceed 40 TDs.

>From the latest 82599 spec update:
"When WTHRESH is set to zero, the software device driver should set the RS bit
in the Tx descriptors with the EOP bit set and at least once in the 40
descriptors."

The fix is to make sure that the distance between TDs with RS bit set
would never exceed HW limit.
As part of that fix, tx_rs_thresh for ixgbe PMD is not allowed to be greater
then to 32 to comply with HW restrictions.

With that fix slight slowdown for the full-featured ixgbe TX path
might be observed (from our testing - up to 4%).

ixgbe simple TX path is unaffected by that patch.

256ff05a9c ixgbe: fix Rx errors statistics for UDP checksum
This patch removes l3_l4_xsum_errors from rx errors.

The reason to remove it is that UDP packets have an optional checksum, and
when not calculated the checksum field should be set to zero. When the
checksum is not calculated (zero-ed out), the hardware still counts a valid
UDP packet as an l3_l4_xsum_error.

This hardware issue is documented in 82599 errata, titled:
"Integrity Error Reported for IPv4/UDP Packets with Zero Checksum"

The solution is to remove l3_l4_xsum_errors from rx_errors, as discussed on
http://thread.gmane.org/gmane.comp.networking.dpdk.devel/25590/

6b6861c171 ethdev: check queue state before starting or stopping
Following the same approach taken with dev_started field
in rte_eth_dev_data structure, this patch adds two new fields
in it, rx_queue_state and tx_queue_state arrays, which track
which queues have been started and which not.

This is important to avoid trying to start/stop twice a queue,
which will result in undefined behaviour
(which may cause RX/TX disruption).

Mind that only the PMDs which have queue_start/stop functions
have been changed to update this field, as the functions will
check the queue state before switching it.

634efbc2c8 mlx5: support RETA query and update
ConnectX-4 adapters do not have a constant indirection table size, which is
set at runtime from the number of RX queues. The maximum size is retrieved
using a hardware query and is normally 512.

Since the current RETA API cannot handle a variable size, any query/update
command causes it to be silently updated to RSS_INDIRECTION_TABLE_SIZE
entries regardless of the original size.

Also due to the underlying type of the configuration structure, the maximum
size is limited to RSS_INDIRECTION_TABLE_SIZE (currently 128, at most 256
entries).

A port stop/start must be done to apply the new RETA configuration.

651c505af8 ring: enhance device setup from rings
The ring ethdev creation function creates an ethdev, but does not
actually set it up for use. Even if it's just a single ring, the user
still needs to create a mempool, call rte_eth_dev_configure, then call
rx and tx setup functions before the ethdev can be used.

This patch changes things so that the ethdev is fully set up after the
call to create the ethdev. The above-mentionned functions can still be
called - as will be the case, for instance, if the NIC is created via
commandline parameters - but they no longer are essential.

The function now also sets rte_errno appropriately on error, so the
caller can get a better indication of why a call may have failed.

b4ae9c505f virtio: optimize ring layout
In DPDK based switching environment, mostly vhost runs on a dedicated core
while virtio processing in guest VMs runs on different cores.
Take RX for example, with generic implementation, for each guest buffer,
a) virtio driver allocates a descriptor from free descriptor list
b) modify the entry of avail ring to point to allocated descriptor
c) after packet is received, free the descriptor

When vhost fetches the avail ring, it need to fetch the modified L1 cache from
virtio core, which is a heavy cost in current CPU implementation.

This idea of this optimization is:
    allocate the fixed descriptor for each entry of avail ring, so avail ring will
always be the same during the run.
This removes L1M cache transfer from virtio core to vhost core for avail ring.
(Note we couldn't avoid the cache transfer for descriptors).
Besides, descriptor allocation and free operation is eliminated.
This also makes vector procesing possible to further accelerate the processing.

This is the layout for the avail ring(take 256 ring entries for example), with
each entry pointing to the descriptor with the same index.
                    avail
                    idx
                    +

+----+----+---+-------------+------+
                    |
                    +

This is the ring layout for TX.
As we need one virtio header for each xmit packet, we have 128 slots available.

734ce47f71 bonding: support RSS dynamic configuration
Bonding device implements independent management of RSS settings. It
stores its own copies of settings i.e. RETA, RSS hash function and RSS
key. It’s required to ensure consistency.

1) RSS hash function set for bonding device is maximal set of RSS hash
functions supported by all bonded devices. That mean, to have RSS support
for bonding, all slaves should be RSS-capable.

2) RSS key is propagated over the slaves "as is".

3) RETA for bonding is an internal table managed by bonding API, and is
used as a pattern to set up slaves. Its size is GCD of all RETA sizes, so
it can be easily used as a pattern providing expected behavior, even if
slaves RETA sizes are different.

ecc1c29df8 mlx5: refactor Rx code for the new verbs RSS API
The new Verbs RSS API is lower-level than the previous one and much more
flexible but requires RX queues to use Work Queues (WQs) internally instead
of Queue Pairs (QPs), which are grouped in an indirection table used by a
new kind of hash RX QPs.

Hash RX QPs and the indirection table together replace the parent RSS QP
while WQs are mostly similar to child QPs.

RSS hash key is not configurable yet.

Summary of changes:

- Individual DPDK RX queues do not store flow properties anymore, this info
  is now part of the hash RX queues.
- All functions affecting the parent queue when RSS is enabled or the basic
  queues otherwise are modified to affect hash RX queues instead.
- Hash RX queues are also used when a single DPDK RX queue is configured (no
  RSS) to remove that special case.
- Hash RX queues and indirection table are created/destroyed when device
  is started/stopped in addition to create/destroy flows.
- Contrary to QPs, WQs are moved to the "ready" state before posting RX
  buffers, otherwise they are ignored.
- Resource domain information is added to WQs for better performance.
- CQs are not resized anymore when switching between non-SG and SG modes as
  it does not work correctly with WQs. Use the largest possible size
  instead, since CQ size does not have to be the same as the number of
  elements in the RX queue. This also applies to the maximum number of
  outstanding WRs in a WQ (max_recv_wr).

Comparing with the older NICs, x550's RSS redirection table is enlarged to 512
entries. As the original code is for the NICs which have a 128 entries RSS table,
it means only part of the RSS table is set on x550. So, RSS cannot work as
expected on x550, it doesn't redirect the packets evenly.
This patch configs the entries beyond 128 on x550 to let RSS work well, and also
update the query and update functions to support 512 entries.

6d7740e2c1 virtio: fix deadloop after wrong config read
The old code adjusts the config bytes we want to read depending on
what kind of features we have, but we later cast the entire buf we
read with "struct virtio_net_config", which is obviously wrong.

The wrong config reading results to a dead loop at virtio_send_command()
while starting testpmd.

The right way to go is to read related config bytes when corresponding
feature is set, which is exactly what this patch does.

685e5fb30b fm10k/base: remove 1588 VF API
Remove support for VF transmit timestamps. VFs should not write the
timestamp bit in the Tx descriptor. Only one Tx timestamp can be
realistically handled at once. It is expected that the switch manager
use FFU logic to disable all timestamp requests except for those
originating from a specific virtual port. It is not possible to
correlate this timestamp accurately if more than one occurs out any
given EPL at a time. Since the primary purpose of Tx timestamps is to
implement PTP daemon, which also requires BAR4 access to change the
clock, do not allow VFs to transmit timestamp. Remove the PF<->VF
message for this behavior.

Note, the VF already didn't have ability to request Tx timestamp mode,
so it essentially wasn't allowed to timestamp before anyways under the
old API.

No longer support old API of request-response timestamp mode messages.
New API only sends timestamp-response when the switch decides which port
will be given control of timestamps. To simplify review of this code,
completely remove the support and re-add support for the response
message in a future patch.

to re-enable the VF again with new settings. This is primarily done in
order to ensure that the switch management software properly clears the
previous VF settings. (ie: switch flow rules and so forth). However,
there is a bug in the flow because we check if VF is enabled and don't
re-enable it at the end. The issue is that we disable the VF in order to
clear switch rules, and never follow-up with a re-enable. This results in
a call to enable the VF results in disabling the logical port.

e78a599651 fm10k/base: fix VF multicast
The VF will send a message to request multicast addresses with the
default vid. In the current code, if the PF has statically assigned a
VLAN to a VF, then the VF will not get the multicast addresses. Fix up
all of the various vlan messages to use identical checks (since each
check was different). Also use set as a variable, so that it simplifies
our check for whether vlan matches the pf_vid.

The new logic will allow set of a vlan if it is zero, automatically
converting to the default vid. Otherwise it will allow setting the PF
vid, or any VLAN if PF has not statically assigned a VLAN. This is
consistent behavior, and allows VF to request either 0 or the
default_vid without silently failing. Note that we need the check for
zero since VFs might not get the default VID message in time to actually
request non-zero VLANs.

Create a function, fm10k_iov_select_vid which implements the logic for
selecting a default vid. This helps us remove duplicate code and
streamlines location of this logic so that we don't make similar bugs in
the future.

00b18e3de1 fm10k/base: fix mailbox phantom messages
The phantom messages were a result of incorrectly forgetting to drop
already transmitted messages. We would reset pulled, and tail_len but
left the head/tail pointers alone.

The correct fix is to loop through pulled and drop messages until we've
dropped at least as many bytes as we pulled (possibly dropping a message
we've only partially transmitted. However, we also have to account for
tail_len variable and the 'ack' value as in mbx_pull_head. This means
that we need to re-read the HEAD field of the mailbox header.

Based on testing, this resolves the phantom messages issue, as well as
correctly keeping messages which have yet to be transmitted at all in
the Tx FIFO. Thus, we will begin re-transmission once we have
re-connected.

63cfcf90fe fm10k/base: ignore oversized mailbox messages
When we call update_max_size, it does not drop all oversized messages.
This is due to the difficulty in performing this operation, since it is
a FIFO which makes updating anything other than head or tail very
difficult. To fix this, modify validate_msg_size to ensure that we error
out later when trying to transmit the message that could be oversized.
This will generally be a rare condition, as it requires the FIFO to
include a message larger than the max_size negotiated during mailbox
connect. Note that max_size is always smaller than rx.size, so it should
be safe to use here.

Also, update the update_max_size function header comment to clearly
indicate that it does not drop all oversized messages, but only those at
the head of the FIFO.

e18683f8ef fm10k/base: scale interrupt on PCIe link speed
Red Rock Canyon's interrupt throttle timers are based on the PCIe link
speed. Because of this, the value being programmed into the ITR
registers must be scaled.

For the PF, this is as simple as reading the PCIe link speed and storing
the result. However, in the case of SR-IOV, the VF's interrupt throttle
timers are based on the link speed of the PF. However, the VF is unable
to get the link speed information from its configuration space, so the
PF must inform it of what scale to use.

Rather than passing this scale via mailbox message, we take advantage of
unused bits in the TDLEN register to pass the scale. It is the
responsibility of the PF to program this for the VF while setting up the
VF queues and the responsibility of the VF to get the information
accordingly. This is preferable because it allows the VF to set up the
interrupts properly during initialization and matches how the MAC
address is passed in the TDBAL/TDBAH registers.

A VF unload followed by a reload incorrectly left this value as 0.
If the VF driver blindly trusted this value it could cause a divide by
zero failure.
Fix this by having stop_hw_vf reset the ITR scale as the device goes
down, similar to the way we handle the MAC address.

To prevent divide-by-zero issues, ensure that we always have an ITR
scale. Default to Gen3 scaling if we don't know the speed. Also ensure
the VF checks the register value and ensures we use Gen3 if we are
provided a zero value.
