d944410a44 enic: fix Tx hang when number of packets > queue size
If the nb_pkts parameter to rte_eth_tx_burst() was greater than
the TX descriptor count, a completion was not being requested
from the NIC, so descriptors would not be released back to the
host causing a lock-up.

Introduce a limit of how many TX descriptors can be used in a single
call to the enic PMD burst TX function before requesting a completion.

71a7e2424e examples/l3fwd: fix using packet type blindly
As a example to use ptype info, l3fwd needs firstly to use
rte_eth_dev_get_supported_ptypes() API to check if device and/or
its PMD driver will parse and fill the needed packet type; if not,
use the newly added option, --parse-ptype, to analyze it in the
callback softly.

As the mode of EXACT_MATCH uses the 5 tuples to caculate hash, so
we narrow down its scope to:
  a. ip packets with no extensions, and
  b. L4 payload should be either tcp or udp.

Note: this patch does not completely solve the issue, "cannot run
l3fwd on virtio or other devices", because hw_ip_checksum may be
not supported by the devices. Currently we can:
  a. remove this requirements, or
  b. wait for virtio front end (pmd) to support it.

a6b450805b examples/l3fwd: fix validation for queue id of config tuple
Added validation for queue id of config parameter tuple.

This validation enforces user to enter queue ids of a port
from 0 and in sequence.

This additional validation on queue ids avoids ixgbe crash caused
by null rxq pointer access inside ixgbe_dev_rx_init.

Reason for null rxq is, L3fwd application allocates memory only for
queues passed by user. But rte_eth_dev_start tries to initialize rx
queues in sequence from 0 to nb_rx_queues,
which is not true and coredump while accessing the unallocated queue .

ae844e5e68 igb: fix crash with offload on 82575
On the 82575 chipset, there is a pool of global TX contexts instead of 2
per queues on 82576. See Table A-1 "Changes in Programming Interface
Relative to 82575" of Intel® 82576EB GbE Controller datasheet (*).

In the driver, the contexts are attributed to a TX queue: 0-1 for txq0,
2-3 for txq1, and so on.

In igbe_set_xmit_ctx(), the variable ctx_curr contains the index of the
per-queue context (0 or 1), and ctx_idx contains the index to be given
to the hardware (0 to 7). The size of txq->ctx_cache[] is 2, and must
be indexed with ctx_curr to avoid an out-of-bound access.

Also, the index returned by what_advctx_update() is the per-queue
index (0 or 1), so we need to add txq->ctx_start before sending it
to the hardware.

(*) The datasheets says 16 global contexts, however the IDX fields in TX
    descriptors are 3 bits, which gives a total of 8 contexts. The
    driver assumes there are 8 contexts on 82575: 2 per queues, 4 txqs.

2a345a8919 mlx4: use dummy Rx queues when non-pow2 number requested
When using RSS, the number of rxqs has to be a power of two.
This is a problem because there is no API in DPDK that makes
the application aware of that.

A good compromise is to allow the application to request a
number of rxqs that is not a power of 2, but having inactive
queues that will never receive packets. In this configuration,
a warning will be issued to users to let them know that
this is not an optimal configuration.

96c0450dff ixgbe: fix dropping packets from unsupported Tx queues
Ixgbe HW supports 128 TX queues. However, the full 128 queues are only
available in VT and DCB mode.  In normal default "none" mode (VT/DCB off)
the maximum number of available queues is only 64.

The driver doesn't check the mode when reporting the available
number of queues, allowing more that 64 queues to be used in all cases.
If a queue no. >=64 is used in default mode, the TX packets will be dropped
silently.

This change adds a check to forbid using a queue number larger than 64
during device configuration (in default mode), so that the problem is
reported as early as possible.

5db6b738c5 ethdev: fix possibly incorrect maximum queues
In rte_eth_dev_configure(), device configuration was copied to the dev
struct after get_dev_info() was called to get the max queue information.
In some drivers, though, the max queues can vary depending on the device
configuration - but that information is not available to the driver until
the copy is made.

This patch moves the memcpy of the device configuration into the dev->data
structure before the call to get_dev_info(), thereby making it accessible
to drivers to use when reporting their max queues.

ca4a155783 ixgbe: fix PF promiscuous mode after VF closed
There's an issue reported. In the scenario DPDK PF + DPDK VF,
if the VF port is closed, PF port cannot receive packets.
I found at that time the promicuous mode is disabled on the PF
port. But it should be enabled.
When VF port is closed, it will send a message to its PF port to
reset it. During this, PF port will also reset its own
promicuous mode. Which promiscuous mode should be set depends on
the parameter stored in the device data. In the function
set_rx_mode, the pointer of device data points to the wrong
address. So, the promiscuous mode is wrong.

To be more specific:
a) it never sets RTE_PTYPE_L2_ETHER

c) it doesn't check is IXGBE_RXDADV_PKTTYPE_ETQF set or not.
While a) is pretty easy to fix, b) and c) are not that straightforward
in terms of SIMD ops (specially b).
So far I wasn't able to make vRX support packet_type properly without

f0aa0e9579 vhost: fix maximum of queues
Currently, the maximum value of rx/tx queues are kept by EAL. But,
the value is used like below with different meanings in vhost PMD.
 - The maximum value of current enabled queues.
 - The maximum value of current supported queues.

This wrong double meaning will cause an issue like below steps.

* Invoke application with below option.
  --vdev 'eth_vhost0,iface=<socket path>,queues=4'
* Configure queues like below.
  rte_eth_dev_configure(portid, 2, 2, ...);
* Configure queues again like below.
  rte_eth_dev_configure(portid, 4, 4, ...);

The second rte_eth_dev_configure() will fail because both
the maximum value of current enabled queues and supported queues
will be '2' after calling first rte_eth_dev_configure().

To fix the issue, the patch adds another variable to keep the maximum
number of supported queues in vhost PMD.

3eabd79c50 virtio: fix Rx ring descriptor starvation
Virtio has an mbuf descriptor ring containing mbufs to be used for
receiving traffic. When the host queues traffic to be sent to the guest, it
consumes these descriptors. If none exist, it discards the packet.

The virtio pmd allocates mbufs to the descriptor ring every time it
successfully receives a packet. However, it never does it if it does not
receive a valid packet. If the descriptor ring is exhausted, and the mbuf
mempool does not have any mbufs free (which can happen for various reasons,
such as queueing along the processing pipeline), then the receive call will
not allocate any mbufs to the descriptor ring, and when it finishes, the
descriptor ring will be empty. The ring being empty means that we will
never receive a packet again, which means we will never allocate mbufs to
the ring: we are stuck.

Ultimately, the problem arises because there is a dependency between
receiving packets and making the descriptor ring not be empty, and a
dependency between the descriptor ring not being empty, and receiving
packets.

To fix the problem, this pakes makes virtio always try to allocate mbufs
to the descriptor ring, if necessary, when polling for packets. Do this by
removing the early exit if no packets were received. Since the packet loop
later will do nothing if there are no packets, this is fine.

I reproduced the problem by pushing packets through a pipelined systems
(such as the client_server sample application) after artificially
decreasing the size of the mbuf pool and introducing a delay in a secondary
stage.

Without the fix, the process stops receiving packets fairly quicky. With
the fix, it continues to receive packets.

65ca78fdf9 enic: fix Rx descriptor limit
On initialization, the rq descriptor count was set to the limit
of the vic.  When the requested number of rx descriptors was
less than this count, enic_alloc_rq() was incorrectly setting
the count to the lower value.  This results in later calls to
enic_alloc_rq() incorrectly using the lower value as the adapter
limit.

2c4ee442c4 ixgbe: fix RETA query and update on X550
For x550 device, the reta table has 512 entries, but in function
ixgbe_dev_rss_reta_query and ixgbe_dev_rss_reta_update we use an
"uint8_t i" to traverse the entries, this will lead the function
to an endless loop.

This patch changes the data type from uint8_t to uint16_t to fix
the issue.

5776c30293 enic: fix error packets handling
If the packet_error bit in the completion descriptor is set, the
remainder of the descriptor and data are invalid. PKT_RX_MAC_ERR
was set in the mbuf->ol_flags if packet_error was set and used
later to indicate an error packet. But since PKT_RX_MAC_ERR is
defined as 0, mbuf flags and packet types and length were being
misinterpreted.

Make the function enic_cq_rx_to_pkt_err_flags() return true for error
packets and use the return value instead of mbuf->ol_flags to indicate
error packets. Also remove warning for error packets and rely on
rx_error stats.
