The network card is a Linksys LNE100TX running at 100 Mbps full-duplex and
dmesg shows the chipset as an ADMtek Comet rev 17. I am using the tulip
driver and it is built into the kernel. The system has an AMD Athlon Tbird
running at 900 MHz so I doubt the system is too slow.
The first time I ran miii-diag it showed the following:
Using the default interface 'eth0'.
Basic registers of MII PHY #1: 3100 7869 001d 2411 05e1 41e1 0007 2001.
The autonegotiated capability is 01e0.
The autonegotiated media type is 100baseTx-FD.
Basic mode control register 0x3100: Auto-negotiation enabled.
Basic mode status register 0x7869 ... 786d.
Link status: previously broken, but now reestablished.
Your link partner advertised 41e1: 100baseTx-FD 100baseTx 10baseT-FD
10baseT.
End of basic transceiver information.
----------
The network card is set to auto-negotiation and mii-diag reported the link
as "previously broken, but now reestablished." Do you think that because
the network card is set to auto-negotiation it is breaking the network
connection and trying to renegotiate the media type and speed thereby
causing the RX errors and overruns?
