In 5.4 kernel old u32 array way of setting network features was dropped and linkmode is now the only way.
So lets migrate the EDMA driver to support linkmode.
Also, old get/set settings API for ethtool is also dropped so lets convert to new ksettings API while at it as it demands linkmode.
Now, gigabit works properly as well as ethtool.
Previously you would get this in ethtool:
root at OpenWrt:/# ethtool eth1
Settings for eth1:
Supports Wake-on: d
Wake-on: d
Current message level: 0x00000000 (0)
Link detected: yes
Now, features are properly advertised:
root at OpenWrt:/# ethtool eth1
Settings for eth1:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Supported pause frame use: Symmetric Receive-only
Supports auto-negotiation: Yes
Supported FEC modes: Not reported
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Advertised pause frame use: Symmetric Receive-only
Advertised auto-negotiation: Yes
Advertised FEC modes: Not reported
Link partner advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Link partner advertised pause frame use: No
Link partner advertised auto-negotiation: No
Link partner advertised FEC modes: Not reported
Speed: 1000Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 4
Transceiver: internal
Auto-negotiation: on
MDI-X: Unknown
Supports Wake-on: d
Wake-on: d
Current message level: 0x00000000 (0)
