Add framework for eventmode helper. Event mode would involve
initialization of multiple devices, like eventdev, ethdev etc.
Add routines to initialize and uninitialize event devices.
Generate a default config for event devices if it is not
specified in the configuration. The routine will iterate
over available event devices and their properties and will
set the config accordingly.

Add event device port-lcore link and specify which event queues should
be connected to the event port. Generate a default config for event
port-lcore links if it is not specified in the configuration. This
routine will check the number of available ports and then create links
according to the number of cores available. This patch also adds a new
entry in the eventmode conf to denote that all queues are to be linked
with every port. This enables one core to receive packets from every port.

Add Rx adapter support. The event helper init routine will initialize
the Rx adapter according to the configuration. If Rx adapter config
is not present it will generate a default config. It will check the
available eth ports and event queues and map them 1:1. So one eth port
will be connected to one event queue. This way event queue ID could
be used to figure out the port on which a packet came in.

Add Tx adapter support. The event helper init routine will initialize
the Tx adapter according to the configuration. If Tx adapter config
is not present it will generate a default config.

Add support for Rx and Tx internal ports. When internal ports are
available then a packet can be received from eth port and forwarded
to event queue by HW without any software intervention. The same
applies to Tx side where a packet sent to an event queue can by
forwarded by HW to eth port without any software intervention.

Add eventmode support to ipsec-secgw. This uses event helper to setup
and use the eventmode capabilities. Add driver inbound worker.
Example command:
./ipsec-secgw -c 0x1 -w 0002:02:00.0,nb_ipsec_in_sa=100 -w 0002:07:00.0
-w 0002:0e:00.0 -w 0002:10:00.1 -- -P -p 0x3 -u 0x1
--config "(0,0,0),(1,0,0)" -f a-aes-gcm-msa.cfg --transfer-mode 1
--schedule-type 2 --process-mode 1 --process-dir 1

of buffers in a pool. Default number of buffers is 4000.

I didn't look at the actual code (yet), just cover letter,
few quick questions below.

Bur right now app can do both inbound and outbound simultaneously on the same core.
I presume the default behavior will be preserved?

For all these parameters, I think better to use names (app/driver, etc.) instead of raw numbers.

By 'library change' you mean that this new event-mode will be supported
only by legacy code-path or ...?

[Anoob] The existing behavior with poll mode thread is not touched. The current changes are only applicable when launched in event-mode.

[Anoob] All the changes are confined to 'examples/ipsec-secgw' directory. Right now, the worker threads make use of the existing routines in non-librte_ipsec mode.

And as I understand, you don't plan to use/support library mode?
I suppose I need to look to the actual code to understand more here.

Ok..., but do we have within DPDK any PMD that implements inline-proto?
AFAIK we don't, but might be I am missing something?

[Anoob] Supporting library mode is also in the pipeline. But initial target would be support with non-librte_ipsec mode.

[Anoob] Inline protocol support would be added to OCTEON TX2 eth PMD in the next cycle. This is an RFC to introduce the idea of using events in ipsec-segcw, which is required for OCTEON TX2 platform to perform inline ipsec processing.
