Subject: [PATCH net-next 5/9] ice: Allow 100M speed for E825C SGMII device

From: Grzegorz Nitka <grzegorz.nitka@...el.com>

Add E825C 10GbE SGMII device to the list of devices supporting 100Mbit
link mode. Without that change, 100Mbit link mode is ignored in ethtool
interface. This change was missed while adding the support for E825C
devices family.

Testing hints (please note, for previous version, 100baseT/Full entry
was missing):
[root@...alhost]# ethtool eth3
Settings for eth3:
        Supported ports: [ TP ]
        Supported link modes:   100baseT/Full
                                1000baseT/Full
                                10000baseT/Full
        Supported pause frame use: Symmetric
        Supports auto-negotiation: Yes
        Supported FEC modes: None
        Advertised link modes:  100baseT/Full
                                1000baseT/Full
                                10000baseT/Full
