Hi,
I have a "Intel Corporation 82572EI Gigabit Ethernet Controller (Copper) (rev
06)" in my CentOS 5.7 (2.6.18-274.7.1.el5 x86_64) box.
I have installed the latest drivers (e1000e-1.10.6.tar.gz) but can't enable
Flow Control:
It seems like Flow Control is enabled when I load the driver, but after that
soon automatically disabled (?):
load driver:
# rmmod e1000e
# modprobe e1000e
# ethtool -a eth0
Pause parameters for eth0:
Autonegotiate: on
RX: on
TX: on
after 1 second:
# ethtool -a eth0
Pause parameters for eth0:
Autonegotiate: on
RX: on
TX: on
after 5 seconds:
# ethtool -a eth0
Pause parameters for eth0:
Autonegotiate: on
RX: off
TX: off
(nothing in /var/log/messages)
If I try to set it via ethtool
# ethtool -A eth0 rx on tx on
# ethtool -a eth0
Pause parameters for eth0:
Autonegotiate: on
RX: off
TX: off
(I see "e1000e: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: None")
I've even tried to force it as a parameter in /etc/modprobe.conf:
options e1000e FlowControl=3
but I get "e1000e: Unknown parameter 'FlowControl'" ...
Any ideas?
Kind regards, Marko Kobal
