From 1b255e1beabf6826758d6018ddd2e1e3bba32f44 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Asbj=C3=B8rn=20Sloth=20T=C3=B8nnesen?= Date: Mon, 15 Sep 2025 14:42:56 +0000 Subject: [PATCH] tools: ynl: add ipv4-or-v6 display hint MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The attribute WGALLOWEDIP_A_IPADDR can contain either an IPv4 or an IPv6 address depending on WGALLOWEDIP_A_FAMILY, however in practice it is enough to look at the attribute length. This patch implements an ipv4-or-v6 display hint, that can deal with this kind of attribute. It only implements this display hint for genetlink-legacy, it can be added to other protocol variants if needed, but we don't want to encourage it's use.
