i want to change the duplex/speed settings on my arm based board,which has a realtek 8210 ethernet card.
running ethtool on my system looks like this
after disabling autonegotiation with #ethtool -s eth0 autoneg off
# ethtool eth0
Settings for eth0:
Supported ports: [ TP AUI BNC MII FIBRE ]
Supported link modes: 10baseT/Half 10baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
Advertised auto-negotiation: Yes
Link detected: yes
After this,when i do
#ethtool -s eth0 duplex half
the duplex settings bcomes half for 1-2 seconds,and then
it again goes back to full duplex mode.
Has anyone faced this problem??
