This patch fixes a trivial typo in the sample apps guide.
commit 35b09d76f8 ("doc: use corelist instead of coremask") replaced
the usage of coremask (-c) with corelist (-l).
As a result of this patch, we have
./build/ipv4_multicast -l 0-3 -n 3 -- -p 0x3 -q 1
in the sample app guide, while the explanation immediately following
says:
In this command:
• The -c option enables cores 0, 1, 2 and 3
This patch fixes the
explanation to have "-l" instead of "-c".

Isolated mode can be requested by applications on individual ports to avoid
ingress traffic outside of the flow rules they define.
Besides making ingress more deterministic, it allows PMDs to safely reuse
resources otherwise assigned to handle the remaining traffic, such as
global RSS configuration settings, VLAN filters, MAC address entries,
legacy filter API rules and so on in order to expand the set of possible
flow rule types.
To minimize code complexity, PMDs implementing this mode may provide
partial (or even no) support for flow rules when not enabled (e.g. no
priorities, no RSS action). Applications written to use the flow API are
therefore encouraged to enable it.
Once effective, leaving isolated mode may not be possible depending on PMD
implementation.

This patch adds support to enable and disable LRO
To support this feature, the driver creates an aggregator ring.
When the hardware starts doing LRO, it sends a tpa_start completion.
When the driver receives a tpa_end completion, it indicates that the
LRO chaining is complete.

This patch adds support to modify MTU using the set_mtu dev_op.
To support frames > 2k, the PMD creates an aggregator ring.
When a frame greater than 2k is received, it is fragmented

Now the driver can support jumbo frames upto 9500 bytes.

1) For a VF, query the firmware to determine if a MAC address is
already configured. If not configure a random default MAC address.
2) Do not initialize the default completion ring in
bnxt_alloc_hwrm_rings().
3) While registering for async events with the firmware,
use func_vf_cfg for a VF and use func_cfg for a PF.
4) Query the VNIC plcmode config using the bnxt_hwrm_vnic_plcmodes_qcfg
before a VNIC is updated. Reconfigure the VNIC with the plcmode
configuration queried earlier. Not doing this could overwrite
the plcmodes in some cases.
5) Reorg the bnxt_handle_fwd_req to properly handle the forwarded

TX coalescing waits for ETH_COALESCE_PKT_NUM packets to be coalesced
across bursts before transmitting them. For slow traffic, such as
100 PPS, this approach increases latency since packets are received
one at a time and tx coalescing has to wait for ETH_COALESCE_PKT
number of packets to arrive before transmitting.
To fix this:
- Update rx path to use status page instead and only receive packets
when either the ingress interrupt timer threshold (5 us) or
the ingress interrupt packet count threshold (32 packets) fires.
(i.e. whichever happens first).
- If number of packets coalesced is <= number of packets sent
by tx burst function, stop coalescing and transmit these packets
immediately.
Also added compile time option to favor throughput over latency by
default.

The DPDK documentation guidelines state that lines should be wrapped as
follows:
* The recommended style for the DPDK documentation is to put sentences on
separate lines. This allows for easier reviewing of patches. ...
* Long sentences should be wrapped at 120 characters +/- 10 characters.
They should be wrapped at words.
http://dpdk.org/doc/guides/contributing/documentation.html#line-length
However, in practice, users almost never submit doc patches in this format.

API changes are planned for 17.08 to made sessions agnostic to the

session can be used on multiple devices.
It requires to change "struct rte_cryptodev_sym_session" to store more
than one private data for devices, as well as remove redundant dev_id
and dev_type.
Effected public functions:
- rte_cryptodev_sym_session_pool_create
- rte_cryptodev_sym_session_create
- rte_cryptodev_sym_session_free
While session will not be directly associated with device, followed API
will be changed adding uint8_t dev_id to the argument list:
- rte_cryptodev_queue_pair_attach_sym_session
- rte_cryptodev_queue_pair_detach_sym_session

This is an ABI change notice for DPDK 17.08 in ethdev
about changes in rte_eth_txmode structure.
Currently Tx offloads are enabled by default, and can be disabled
using ETH_TXQ_FLAGS_NO* flags. This behaviour is not consistent with
the Rx side where the Rx offloads are disabled by default and enabled
according to bit field in rte_eth_rxmode structure.
The proposal is to disable the Tx offloads by default, and provide
a way for the application to enable them in rte_eth_txmode structure.
Besides of making the Tx configuration API more consistent for
applications, PMDs will be able to provide a better out of the
box performance.
Finally, as part of the work, the ETH_TXQ_FLAGS_NO* will
be superseded as well.

The PCI and virtual bus are planned to be moved to the generic
drivers/bus directory in v17.08. For this change to be possible, the EAL
must be made completely independent.
The rte_devargs structure currently holds device representation internal
to those two busses. It must be made generic before this work can be
completed.
Instead of using either a driver name for a vdev or a PCI address for a
PCI device, a devargs structure will have to be able to describe any
possible device on all busses, without introducing dependencies on
any bus-specific device representation. This will break the ABI for this
structure.
Additionally, an evolution will occur regarding the device parsing
from the command-line. A user must be able to set which bus will handle
which device, and this setting is integral to the definition of a
device.
The format has not yet been formally defined, but a proposition will
follow soon for a new command line parameter format for all devices.
