Add devargs to control each event timer adapter i.e. TIM rings internal
parameters uniquely. The following dict format is expected
[ring-chnk_slots-disable_npa-stats_ena]. 0 represents default values.

--dev "0002:0e:00.0,tim_ring_ctl=[2-1023-1-0]"

Add devargs to limit the max number of TIM rings reserved on probe.
Since, TIM rings are HW resources we can avoid starving other
applications by not grabbing all the rings.

Add devargs support to modify number of chunk slots. Chunks are used to
store event timers, a chunk can be visualised as an array where the last
element points to the next chunk and rest of them are used to store
events. TIM traverses the list of chunks and enqueues the event timers
to SSO.
If no argument is passed then a default value of 255 is taken.
Example:
--dev "0002:0e:00.0,tim_chnk_slots=511"

If the chunks are allocated from NPA then TIM can automatically free
them when traversing the list of chunks.

- Allocate a TIM lf based on number of lf's provisioned.
- Verify the config parameters supplied.

SSO GGRPs i.e. queue uses DRAM & SRAM buffers to hold in-flight
events. By default the buffers are assigned to the SSO GGRPs to
satisfy minimum HW requirements. SSO is free to assign the remaining
buffers to GGRPs based on a preconfigured threshold.
We can control the QoS of SSO GGRP by modifying the above mentioned
thresholds. GGRPs that have higher importance can be assigned higher
thresholds than the rest.
Example:
--dev "0002:0e:00.0,qos=[1-50-50-50]" // [Qx-XAQ-TAQ-IAQ]
Qx -> Event queue Aka SSO GGRP.
XAQ -> DRAM In-flights.
TAQ & IAQ -> SRAM In-flights.
The values need to be expressed in terms of percentages, 0 represents
default.

Octeontx2 SSO by default is set to use dual workslot mode.
Add devargs option to force legacy mode i.e. single workslot mode.
Example:
--dev "0002:0e:00.0,single_ws=1"
Signed-off-by: Pavan Nikhilesh <pbhagavatula@marvell.com>
OcteonTx2 AP core SSO cache contains two entries each entry caches
state of an single GWS aka event port.
AP core requests events from SSO by using following sequence :
1. Write to SSOW_LF_GWS_OP_GET_WORK
2. Wait for SSO to complete scheduling by polling on SSOW_LF_GWS_TAG[63]
3. SSO notifies core by clearing SSOW_LF_GWS_TAG[63] and if work is
valid SSOW_LF_GWS_WQP is non-zero.
The above sequence uses only one in-core cache entry.
In dual workslot mode we try to use both the in-core cache entries by
triggering GET_WORK on a second workslot as soon as the above sequence
completes. This effectively hides the schedule latency of SSO if there
are enough events with unique flow_tags in-flight.
This mode reserves two SSO GWS lf's for each event port effectively
doubling single core performance.
Dual workslot mode is the default mode of operation in octeontx2.

The default policy for offload-specific fields is that
they are undefined unless the corresponding offloads are
requested in mbuf ol_flags. This is also the case for outer
L2 and L3 length fields which must not be assumed to contain
zeros for non-tunnel packets. The patch clarifies this behaviour
in the comments and also adds appropriate checks to the PMDs which
do not check any tunnel-related offloads before using the said fields.
