Hi,
I would really appreciate your help.
These are my ethernet driver settings:
>ethtool -i eth0
driver: igb
version: 3.0.6-k2
firmware-version: 3.2-3
bus-info: 0000:01:00.0
And ethernet device properties:
>ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
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: 1
Transceiver: internal
Auto-negotiation: on
MDI-X: Unknown
Supports Wake-on: pumbg
Wake-on: g
Current message level: 0x00000003 (3)
drv probe
Link detected: yes
The pause parameters are as follows:
>ethtool -a eth0
Pause parameters for eth0:
Autonegotiate: on
RX: on
TX: on
When I type in:
>ethtool -A rx off tx off
It has no effect on the pause parameters:
>ethtool -a eth0
Pause parameters for eth0:
Autonegotiate: on
RX: on
TX: on
When I turn off the autoneg pause parameter, I am allowed to modify tx and rx:
>ethtool -A eth0 rx off tx off autoneg off
Pause parameters for eth0:
Autonegotiate: off
RX: off
TX: off
Why am I not allowed to modify the tx and rx pause parameters when the autoneg
pause parameter is on?
Also, how can I set the Advertised pause frame so that it
s tx-only or tx&rx?
Also, I am allowed to change the pause parameters when the auto-negotiated
duplex is half, but not when duplex is full.
Thanks for your help,
Bilal
