    My configuration : a server with 2 cards NE2000(10 Mbps), a machine with
    2 cards : 1 NE2000(ISA) and 1 3C905b(PCI).
    server : NE2000 <-> workstation : NE2000 in 192.168.1.X
    server : NE2000 <-> workstation : 3C905b in 192.168.0.X

    I try with a 2.4.6, 2.4.15, and 2.5.31. there is near from no
    differences in the code of ne.c, gkrellm tells me that when I download
    on both cards big files (for tests), the bandwidth falls to 5Mbps for
    each card.
    If 1 download stops, the other bandwidth is up to 10Mbps immediatly.

    No other ISA card is used on the server.
