Command show-port should show RSS info (rss_key, len and rss_hf),
However, the information is showned only when rss_conf.rss_key is not
NULL. Since no memory is allocated for rss_conf.rss_key, rss_key
will always be NULL and the rss_info will never show. This patch
allocates memory for rss_conf.rss

The issue arose due to the change in the DPDK read-write lock
implementation. That change added a new flag, RTE_RWLOCK_WAIT, designed
to prevent new read locks while a write lock is in the queue. However,
this change has led to a scenario where a recursive read lock, where a
lock is acquired twice
This patch introduces the generic RTE_CACHE_GUARD macro into the EAL, and
replaces vaguely described empty cache lines in the rte_ring structure
with this macro.

Hello,
When creating a ring, we need to know the maximum length of the name.
It seems this value is not documented.
And there is no constant defined.
There is only RTE_MEMZONE_NAMESIZE.
Should we document the maximum length as 31 and add a constant?
#define RTE_RING_NAME_SIZE RTE_MEMZONE_NAMESIZE

The purpose of the dispatcher library is to decouple different parts
of an eventdev-based application (e.g., processing pipeline stages),
sharing the same underlying event device.
The dispatcher replaces the conditional logic (often, a switch
statement) that typically follows an event device deque
The purpose of the dispatcher library is to help reduce coupling in an

In addition, the dispatcher also provides a convenient and flexible
