dhcpcd-discuss

Hi,

There's a bug report in Debian[0] that I can reproduce in dhcpcd 7.1.0.
Essentially, setting a static interface_mtu doesn't seem to work as
expected, though I am not sure if this configuration is even supported?

Here's the interface configuration snippet - note the third line:

    interface ens3
    noipv6rs
    static interface_mtu=1400
    static ip_address=192.168.122.9/24
    static routers=192.168.122.1
    static domain_name_servers=192.168.122.1

And here's the resulting interface - mtu 1500, when I would have
expected 1400:

    2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
        link/ether 52:54:00:ba:4e:d6 brd ff:ff:ff:ff:ff:ff
        inet 192.168.122.9/24 brd 192.168.122.255 scope global noprefixroute ens3
           valid_lft forever preferred_lft forever
        inet6 fe80::6486:7fbd:bf43:e57e/64 scope link 
           valid_lft forever preferred_lft forever

Is there a bug here, is the configuration wrong, or is this simply not
supported?

Thanks!
