I have read the comment but that is not my case.

As you said, the behave of the HW is wired really.
My Japanese workmate Ohsaki had solved it by comment out the following line
        bus_space_write_2(bst, bsh, RECV_CONTROL_REG_W, RCR_SOFTRESET);
at the beginning part of the smc91cxx_init function in file
dev/ic/smc91cxx.c.
It looks like the high value in RCR_SOFTRESET
(The Soft RESET bit in Receive Control Register at Bank0 will prevent this
card from being brought up, Why?)
LAN91C111 is working now.
I will try other methods to solve this if there is time.

Thanks a lot again.
