I tried But no help neither.
I peek into the e1000 kernel driver files, and in the file
/drivers/net/e1000/e1000_ethtool.c we can find that 82543 gigabit's
transceiver is get|set to "external". It means that either driver
problem or the underlying hardware is crazy, or I'm too dumb :)
Another thing don't quite understand is, There are NO
e1000_media_type_RJ45 defined in e1000_hw.h file, only
e1000_media_type_copper and e1000_media_type_fiber.
Please help.
Related sections from e1000_hw.h and e1000_ethtool.c are attached
below.
/* from e1000_hw.h */
......
, only /* Media Types */
typedef enum {
e1000_media_type_copper = 0,
e1000_media_type_fiber = 1,
e1000_media_type_internal_serdes = 2,
e1000_num_media_types
} e1000_media_type;
.......
/* from e1000_ethtool.c */
.......
static int
e1000_get_settings(struct net_device *netdev, struct ethtool_cmd *ecmd)
{
struct e1000_adapter *adapter = netdev->priv;
struct e1000_hw *hw = &adapter->hw;
if(hw->media_type == e1000_media_type_copper) {
.......
ecmd->advertising |= hw->autoneg_advertised;
}
ecmd->port = PORT_TP;
ecmd->phy_address = hw->phy_addr;
if(hw->mac_type == e1000_82543)
ecmd->transceiver = XCVR_EXTERNAL;
else
ecmd->transceiver = XCVR_INTERNAL;
} else {
......
if(hw->mac_type >= e1000_82545)
ecmd->transceiver = XCVR_INTERNAL;
else
ecmd->transceiver = XCVR_EXTERNAL;
}
......

one thing I've noticed with ethtool is that you have to bring down the
interface to make the change soemtimes, so try
ifdown eth1;ethtool -s eth1 xcvr internal;ifup eth1
