From 9a834c0112b0987bbbb173f6da67d3c111aeecad Mon Sep 17 00:00:00 2001 From: Mohsin Kazmi Date: Mon, 10 Feb 2025 11:19:47 +0000 Subject: ip: add support to preallocate pools MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Type: improvement In certain use cases, the underlying pools expand by allocating a new, larger pool and copying the existing elements into it. This process can be time-consuming, leading to slower control plane configurations, especially when a large number of elements are already present. This patch allows users to pre-configure some of these pools through startup.conf. It also fixes alignment for ip4 mtrie.
