From e66f7075ee12ae3107d29efaf683442c3535e8b9 Mon Sep 17 00:00:00 2001 From: Indrajit Raychaudhuri Date: Sat, 23 Sep 2023 23:44:08 -0500 Subject: mdns: T5615: Allow controlling IP version to use for mDNS repeater This commit adds a new configuration option to the mDNS repeater service to allow controlling which IP version to use for mDNS repeater. Additionally, publishing AAAA record over IPv4 and A record over IPv6 is disabled as suggested.
