From 2152722bd3f95878dfdc9071054ceb59e36217bb Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 13 Mar 2019 12:45:13 +0100 Subject: [PATCH] netifd: add support for suppressing the DHCP request hostname by setting it to * dnsmasq (and probably other DHCP servers as well) does not like to hand out leases with duplicate host names.
