In poll mode driver of octeontx2 the RQ is connected to a CQ and it is
responsible for asserting backpressure to the CGX channel.
When event eth Rx adapter is configured, the RQ is connected to a event
queue, to enable backpressure we need to configure AURA assigned to a
given RQ to backpressure CGX channel.
Event device expects unique AURA to be configured per ethernet device.
If multiple RQ from different ethernet devices use the same AURA,
the backpressure will be disabled, application can override this
using devargs:

SSO HWGRPs i.e. queue uses DRAM & SRAM buffers to hold in-flight
events. By default the buffers are assigned to the SSO HWGRPs to
satisfy minimum HW requirements. SSO is free to assign the remaining
buffers to HWGRPs based on a preconfigured threshold.
We can control the QoS of SSO HWGRP by modifying the above mentioned
thresholds. HWGRPs 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.
