dec 21143 : Problem FULLDUPLEX Performance

[Massimo Lambertini]

Hi .

I use linux redhat 6.0  kernel 2.2.9 on my dual pII 500 ,
with a netcard 21143 ( labeled Intel ), works fine
when i set manually to options 13 that disable fullduplex .

The system in half duplex perform 5Mbytes/s transfer
but in autodetect ( netcard in 100TX FD) the performance
descrease to 200Kbytes/s .

I have tryed varius switch , and i've changed the netcard,
but the problem persist .

Have anyone a solution
Thank you very much for any respose or solution .
