    Also of interest: in July 2003, Glen Turner of AARNet (glen.turner+spam@aarnet.edu.au) mentioned:

    I went through all the ethernet driver code in the Linux 2.4 kernel.
    The following drivers support 9000 MTU packets:
        tg3       Broadcom gigabit
        e1000     Intel gigabit
        acenic    Alteon AceNIC, 3Com 3c985, 3Com 3c985B, Netgear GA620,
                  HP, SGI, DEC.
        amd8111e  Claims support, but only 8K
        d12k      (DLink) Claims support, but only 8000
    Everything else in the stock kernel is 1500.  The tc902x
    driver used by the Antares cards isn't in the stock kernel.
    The drivers which work can also do VLANs at 9000 MTU for
    the encapsulated packets.
    For people looking for a GbE card for Linux the "Intel Pro/1000
    Server MT" is currently the best choice of the popular cards.
    The e1000 driver fully supports the hardware features, including
    interrupt combining and large send offload.
    People using Broadcom cards have a hard time of it.  The
    manufacturer's bcm5700 driver doesn't work well with the
    kernel.  The tg3 driver doesn't work well with the card.
    Things are improving, but large send offload, etc are
    still some time away.
