Package: dhcpcd5 Version: 6.10.1-1 Severity: normal Tags: upstream Dear Maintainer,
To use a static IP configuration, e.g. the following lines can be added to /etc/dhcpcd.conf: interface eth0 static ip_address=192.168.1.10/24 static routers=192.168.1.1 static domain_name_servers=192.168.1.1 Using these settings only, everything works as expected (no DHCP requests, simply apply config). To specify a non-standard MTU, the following additional line is required: static interface_mtu=1400 The configuration file is still successfully parsed, but the MTU setting is NOT applied to the interface. Having a look at the source code shows that the "static interface_mtu" case is explicitly handled in the parser routine, so the specified value is expected to be applied during interface confiuration. However, it seems that the MTU handling is unintentionally bypassed in the static configuration use case.
