Applied to dpdk-next-net-eventdev/for-main after following changes. Thanks

1) Removed stale dlb section in MAINTAINERS file
2) Removed stale dlb reference from app/test/test_eventdev.c
3) Updated git commit message to
event/dlb: remove dlb driver

Remove event/dlb driver from dpdk code base.
Updated release note's removal section to reflect the same.

> -Atomic Inflights Allocation
> -~~~~~~~~~~~~~~~~~~~~~~~~~~~
> -
> -In the last stage prior to scheduling an atomic event to a CQ, DLB holds
> the
> -inflight event in a temporary buffer that is divided among load-balanced
> -queues. If a queue's atomic buffer storage fills up, this can result in
> -head-of-line-blocking. For example:
> -
> -- An LDB queue allocated N atomic buffer entries
> -- All N entries are filled with events from flow X, which is pinned to CQ
> 0.
> -
> -Until CQ 0 releases 1+ events, no other atomic flows for that LDB queue can
> be
> -scheduled. The likelihood of this case depends on the eventdev
> configuration,
> -traffic behavior, event processing latency, potential for a worker to be
> -interrupted or otherwise delayed, etc.
> -
> -By default, the PMD allocates 16 buffer entries for each load-balanced
> queue,
> -which provides an even division across all 128 queues but potentially
> wastes
> -buffer space (e.g. if not all queues are used, or aren't used for atomic
> -scheduling).
> -
> -The PMD provides a dev arg to override the default per-queue allocation.
> To
> -increase a vdev's per-queue atomic-inflight allocation to (for example)

> -Deferred Scheduling
> -~~~~~~~~~~~~~~~~~~~
> -
> -The DLB PMD's default behavior for managing a CQ is to "pop" the CQ once
> per
> -dequeued event before returning from rte_event_dequeue_burst(). This frees
> the
> -corresponding entries in the CQ, which enables the DLB to schedule more
> events
> -to it.
> -
> -To support applications seeking finer-grained scheduling control -- for
> example
> -deferring scheduling to get the best possible priority scheduling and
> -load-balancing -- the PMD supports a deferred scheduling mode. In this
> mode,
> -the CQ entry is not popped until the *subsequent*
> rte_event_dequeue_burst()
> -call. This mode only applies to load-balanced event ports with dequeue
> depth of
> -1.
> -
> -To enable deferred scheduling, use the defer_sched vdev argument like so:
> -
> -    .. code-block:: console
> -
> -       --vdev=dlb1_event,defer_sched=on
