Subject: [PATCH v1 3/4] eal: rename socket ID to NUMA ID in internal config
Date: Tue, 26 Nov 2024 13:14:49 +0000	[thread overview]
Message-ID: <0cacb7d0789f03163ed32faa9d6919cbfe690b52.1732626792.git.anatoly.burakov@intel.com> (raw)
In-Reply-To: <cover.1732626792.git.anatoly.burakov@intel.com>

This patch renames socket ID-related fields in internal EAL config
structure to refer to NUMA ID instead. No user-facing API's are changed.
