紧急求助:DE2上的DM9000A使用问题..

我想在nios上跑uClinux,使用DM9000A做下网络通信。我看了别人的帖子,内核是这么配置的:
Networking -->
  • Networking support
    Networking options --->
    <*> Packet socket
    <*> Unix domain sockets
  • TCP/IP networking

    Device Drivers -->Network device support ─>
  • Network device support
  • Ethernet (10 or 100Mbit)


  • SMC 91C9x/91C1xxx support              # only if you use Altera Nios dev board with SMC91111,
    [ ] Opencores (Igor) Emac support                 
    [ ] MoreThanIP 10_100_1000 Emac support
    [ ] DM9000 support  
  • DM9000A with checksum offloading      # only if you use DE2 with DM9000A

    但是uClinux内核里面没有"DM9000A with checksum offloading"这一项,只有"DM9000 support".
    不知道用DE2跑 uClinux的朋友是怎么做的?
    非常着急啊...
