Hello, recently I wrote a virtual network card driver of vxworks and suffered some questions .
The driver works as follows: When receiving the data, the driver receives MAC data frames from FPGA and deals with them . Then put some MAC frames into TCP/IP protocol stack of vxorks . And receive the datas by socket program in application level. When sending the data, useing socket program to send the datas. And get the datas from endSend() function of the driver. Then send the datas to FPGA.
Now, I have done the driver and loaded it manually. The muxDevload(), musDevstart(),ipAttach(),ifMaskset(),ifAddrSet() functions all can be executed correctly and the ifShow()and muxShow() command shows that everything is correct. But when I writed a socket program for testing the driver, the endSend() function didn't be called at all. It looks common form the loading process, but why the endSend() function not been called?
