Hi,

 Anyone know why Intel 82543 gigabit cards report lots of carrier
problems?  I don't know why Intel 82543 gigabit network card using
external transceiver(reported by ethtool) since it is directly
connected to HP Switch with CAT-6 RJ45 network cables. Any one can
explain where is the external transceiver for the Intel 82543 cards? 
I tried to run "ethtool âs eth1 xcvr internal" trying to set its
transreciver to internal(on-board) but the operation fails silently.
Please help.

 In contrast, Intel 82540 gigabit cards reports no carrier problems at
all, and use internal transceiver(reported by ethtool).

 The following are the output of commands ethtool and ifconfig:

[root dumbboy root]# ifconfig eth1 | grep carrier

          TX packets:56944847 errors:0 dropped:0 overruns:0 carrier:39363496

[root dumbboy root]# ethtool -S eth1 | grep -E 'carrier|tx_packets'

     tx_packets: 57027012

     tx_carrier_errors: 39417377

[root dumbboy root]# ethtool eth1
