use NIC EEPro100+ on INTEL STL2 motherboard, with "eepro100" driver - all work ok.
or "e100" driver and with patch:
--- drivers/net/e100/e100.h- Wed Dec 4 15:16:08 2002 +++ drivers/net/e100/e100.h Wed Dec 4 15:16:20 2002 @@ -100,7 +100,7 @@ #define E100_MAX_NIC 16 -#define E100_MAX_SCB_WAIT 100 /* Max udelays in wait_scb */ +#define E100_MAX_SCB_WAIT 5000 /* Max udelays in wait_scb */ #define E100_MAX_CU_IDLE_WAIT 50 /* Max udelays in wait_cus_idle */ /* HWI feature related constant */ all work ok.
