Subject: [PATCH] examples/l3fwd: extend NUMA nodes limit beyond 8
Date: Fri, 26 Dec 2025 08:17:19 +0000 [thread overview]
Message-ID: <20251226081719.1120313-1-wangliangxing@hygon.cn> (raw)
For platforms with more than 8 NUMA nodes, the l3fwd example fails when
using cores on NUMA node 8 or above.
Use RTE_MAX_NUMA_NODES instead of 8 to extend NUMA nodes limit.
