[dpdk-dev] [PATCH v2] event/cnxk: reduce max timer chunk pool cache size

[Shijith Thotton <sthotton@marvell.com>]

Reduced max chunk pool cache size from RTE_MEMPOOL_CACHE_MAX_SIZE(512)
to 128.

If chunk pool cache is empty, it gets filled during arm. Filling 512
entries at a time will fail arm if timeout is shorter.

Fixes: 0e792433d051 ("event/cnxk: create and free timer adapter")
