vxworks中實(shí)現(xiàn)雙網(wǎng)卡驅(qū)動(dòng)的例子

 以3Com3c905b與ne2000(i/o基址0xfcc0,i/o中斷10)兩塊網(wǎng)卡為例：

1.在config.h中,

#define INCLUDE_ENE

#define INCLUDE_EL_3C90X

#define IO_ADRS_ENE 0x0fcc0

#define INT_LVL_ENE 0x0a

2.make bootrom

3.host邊，開FTP服務(wù)

3.下載vxworks,假設(shè)啟動(dòng)網(wǎng)卡為ene.

4.在shell下，將另一塊網(wǎng)卡綁上去:

-> usrNetEndDevStart "elPci",0 (假設(shè)啟動(dòng)的網(wǎng)卡為ne2000)

-> usrNetIfConfig "elPci",0,"138.203.175.6","host name",0xffffff00

注意：在生成vxworks時(shí)，IP_MAX_UNIT參數(shù)改成2. 兩個(gè)網(wǎng)卡的ip地址要在不同的子網(wǎng)下。
