Exactly.  And that is why I had requested the output of ethtool. 

I just installed a fresh copy of F27/KDE from the Live-ISO.  Bringing up the
Network-Manager GUI one sees

Allow Auto-negotiation:  Unchecked
Speed:  Automatic
Duplex: Half

The hardware is
 00:03.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller

The driver in use is (from lsmod) e1000.

The ifcfg-enp0s3 file contains...

[egreshko@f27k-v network-scripts]$ cat ifcfg-enp0s3
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=enp0s3
UUID=7f87f7d8-1d0f-316e-9a2c-419042156b19
ONBOOT=yes
AUTOCONNECT_PRIORITY=-999
DEVICE=enp0s3

(No, ETHTOOL_OPTS= line)

And ethtool reports....

Settings for enp0s3:
        Supported ports: [ TP ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
        Supported pause frame use: No
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
        Advertised pause frame use: No
        Advertised auto-negotiation: Yes
        Speed: 1000Mb/s
        Duplex: Full
        Port: Twisted Pair
        PHYAD: 0
        Transceiver: internal
        Auto-negotiation: on
        MDI-X: off (auto)
Cannot get wake-on-lan settings: Operation not permitted
        Current message level: 0x00000007 (7)
                               drv probe link
        Link detected: yes

So, what the GUI has and what reality is are different.   Possibly a function of the
driver?

Oh, well....  I suppose I'll follow the BZ.
