From f6c8f5e8694c7a78c94e408b628afa6255cc428a Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Wed, 20 Mar 2024 19:02:14 -0700 Subject: [PATCH] tools: ynl: fix setting presence bits in simple nests When we set members of simple nested structures in requests we need to set "presence" bits for all the nesting layers below. This has nothing to do with the presence type of the last layer.
