I am trying to find a solution to get data link layer information from an Ethernet card(Realtek-8139).
I need information such as FCS failed or not?, operating speed of interface, medium busy or not?
full duplex or half duplex...I'm using Linux 2.4 kernel. Is it possible to retrieve this kind of information from ethernet driver?..Will any API work out for this?.. I'm in big trouble!! pls help me out.

Thanks in advance..
