With existing devlink API could this be modelled by three ingress pool
I hope that is not true, since we (Netronome) are trying to use it for
NIC configuration, too. We should generalize the API if need be.
Yes, it is up to your company. devlink is static tool. DCBNL are intended to
be dynamically configured by switch. In real world, not many people

From: Huy Nguyen
In this patch, we add dcbnl buffer attribute to allow user
change the NIC's buffer configuration such as priority
to buffer mapping and buffer size of individual buffer.
This attribute combined with pfc attribute allows advance user to
fine tune the qos setting for specific prio
