Hi,

after upgrading a machine to 15.6, one of its network interfaces no longer comes up during boot:

```
Jul 15 15:08:55 falkor21.infra.opensuse.org wickedd[15284]: os-f-nfs: unable to send arp packet: No buffer space available
Jul 15 15:08:56 falkor21.infra.opensuse.org wickedd[15284]: os-f-nfs: unable to send arp packet: No buffer space available
Jul 15 15:08:56 falkor21.infra.opensuse.org wickedd[15284]: os-f-nfs: ARP verify failed for 192.168.202.21 - max (3) retry!
```

Manually running `ifup all` after the boot brings it up successfully.
The only difference with this interface is that it is using IPv4 addressing. All other interfaces on this machine only use IPv6.

Any ideas?

Some more details:

```
falkor21 (Hypervisor):~ # grep -v '^#' /etc/sysconfig/network/ifcfg-os-f-nfs
IPADDR_1='192.168.202.21/24'
STARTMODE='auto'
ETHERDEVICE='bond-ob'
VLAN_ID='3329'
FIREWALL='no'
BOOTPROTO='static'
falkor21 (Hypervisor):~ # rpm -qa kernel* wicked*
wicked-service-0.6.75-150600.11.3.4.x86_64

```

Journal output is attached (note there are also some kernel errors in it, those I reported over in #1227720).
