Okay, I have a Fedora release 23 install. Everything work great....well that's
until I reboot (re-IPL). There is an inconsistency in the initialization of
the Ethernet interfaces:
1) Interfaces come up w/o an IP address (see enccw0.0600 and enccw0.0700
ifconfig
enccw0.0.0600: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 02:00:01:00:00:1f txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
enccw0.0.0700: flags=4097<UP,MULTICAST> mtu 1492
ether 02:00:01:00:00:20 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1 (Local Loopback)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
inet 192.168.122.1 netmask 255.255.255.0 broadcast 192.168.122.255
ether 52:54:00:df:e7:ba txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
2) One comes up (although w/o an IP address) and the other doesn't come up
at all
ifconfig
enccw0.0.0700: flags=4097<UP,MULTICAST> mtu 1492
ether 02:00:01:00:00:20 txqueuelen 1000 (Ethernet)

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1 (Local Loopback)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
inet 192.168.122.1 netmask 255.255.255.0 broadcast 192.168.122.255
ether 52:54:00:df:e7:ba txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
3) Both interfaces come up normally:
ifconfig
enccw0.0.0600: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 4096
inet 10.1.20.84 netmask 255.255.0.0 broadcast 10.1.255.255

RX packets 1542 bytes 182508 (178.2 KiB)
RX errors 0 dropped 98 overruns 0 frame 0
TX packets 46 bytes 4642 (4.5 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
enccw0.0.0700: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 4096
inet 192.168.199.84 netmask 255.255.255.0 broadcast 192.168.199.25

TX packets 26 bytes 2962 (2.8 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1 (Local Loopback)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
inet 192.168.122.1 netmask 255.255.255.0 broadcast 192.168.122.255
ether 52:54:00:df:e7:ba txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
I'm not seeing any differences in the startup messages, so I'm a bit puzzled.
(I also have a SUSE-SLES12 that doesn't experience this behavior)
